 * Some other may also benefit from this...
 * We can't ask for huge chunks of memory in a context where
 * the caller can't be put to sleep (like, here.)  The alloc
 * is likely to fail.  Instead we do this: the first time we
 * get called, kick off a thread to do the allocation.  Return
 * immediately to the caller with EAGAIN, as an indication that
 * they should send down the ioctl again.  By the time the
 * second call comes in it's likely that the memory allocation
 * thread will have returned with the requested memory.  We will
 * continue to return EAGAIN however until the thread has completed.
 * When it has, we return zero (and the memory) if the allocator
 * was successful and ENOSR otherwise.
 *
 * Callers of the RCOMP and XCOMP ioctls are encouraged (but not
 * required) to loop for some number of iterations with a small
 * delay in the loop body (for instance a 1/10-th second "sleep"
 * via select.)
