+This is the pthread implementation of dietlibc.
+Written from scratch by Olaf Dreesen.
+
+Thu Apr 12 16:47:12 MEST 2001
+
+ added conditional variables...
+ except pthread_cond_timedwait all should work man-page like
+ pthread_cond_timedwait dosen't handle cancel request according to man-page
+
+ added thread specific key handling (all according to man-page)
+
+Fri Mar 30 18:47:37 MEST 2001
+
+ uff found some logic errors and fixed them.
+ pthread_create had a problem with user provided stacks.
+
+
+Fri Mar 23 14:09:54 MET 2001
+
+ arg.. the kernel-header are so inconsistent...
+ on x86 it works on arm and sparc not due to MISSING defines, miss-places
+ includes and __KERNEL__ checks....
+ the best in this category is that the kernel-header are changed that the
+ buggy (g)libc haven't to change... (f..k glibc, the headers HAVE to be
+ CONSISTENT)
+ a public defined symbol on arch X have to be in Y to unless marked...
+ that is mainly speaking SCHED.H ! arg....
+
+
+Wed Mar 14 04:28:45 MET 2001
+
+ I have implemented the "Manager Thread" so that nested thread creation
+ works. really ugly stuff... don't look at it unless you're sitting on solid
+ ground.
+
+
+Mon Mar 12 16:16:00 CET 2001
+
+ first of all:
+ I strongly suggest NOT to use it yet, it's very, very, ... very
+ experimental. I guess you got the point. there is still much debug code,
+ incomplete functions and unusable states....
+
+ I'm still working on the final alpha...

+LIBPTHREAD
+
+ This is the pthread implementation of dietlibc.
+ Written from scratch by Olaf Dreesen.
+
+1. STATUS: incomplete but should work (or not... I had a lot of heisen-bugs...)
+ On non i386 archs the kernel header have major differences...
+ NO workaround yet for this problems...
+
+It's like linuxthreads a clone base thread implementation.
+
+I have implemented a "Manager Thread" with all the pain it involves...
+Nested thread creation is now working fine...
+
+
+2. HOW-TO make this lib:
+
+ 1. generate the dietlibc in the parent directory.
+ and make sure you have WANT_THREAD_SAVE active in the file:
+ dietfeatures.h
+
+ 2. change back here and type make
+
+ and then you should have a libpthread.a
+
+
+3. NOTES
+
+NON STANDARD SIGNAL HANDLING for the threads:
+
+ SIGHUP the targeted thread is canceled
+ depends on the cancel type of the thread.
+
+ ASYNCHRONOUS: the signal handler will KILL the thread immediately.
+
+ DEFERRED: the signal handler mark its thread as canceled.
+ (only for the sig-handler to do some sane stuff...)
+
+ SIGTERM the thread is KILLED
+ if the thread signaled is the main thread, then ALL child-threads
+ will get a SIGHUP and after some micros a SIGTERM....
+
