e8dd1efe84 Implement --weird-hacks=truncate-writes to limit the size of write syscalls 
to 4096, to possibly avoid deadlocks under very rare circumstances.
Is fully documented and commented.

5bf10a3618 cleanup_after_thread_exited: also clean up the waiting_fds table on thread 
disappearance.  This fixes an assertion failure to do with thread nukage
on fork():
   vg_scheduler.c:936 (poll_for_ready_fds):
   Assertion `vgPlain_is_valid_tid(tid)' failed.

a077c2c8ac Make __pthread_clock_gettime and __pthread_clock_settime appear for

7bcbe59c1f Fix subtle bug in the interaction between pthread_create and thread_wrapper, 
exposed by scheduling changes caused by commit vg_scheduler.c rev 1.70.
We cannot simply pass the __attr pointer to the child, since it could
point to stuff on the parent's stack, which might not exist by the time
the child looked at it.  Prior to scheduler.c rev 1.70 the child would
have been scheduled as soon as created, so the access was made before the
parent could clear the stuff from its stack.  From rev 1.70 and after
the parent continues after creating the child, causing invalid stack
accesses when the child finally runs.

711baa5d1c Rationalise client-request handling a bit, by merging the two switches 
into one.  This can change the scheduling a bit since the policy of
running the same thread after the request if it is possible now applies
to _all_ requests.

seems to lead to a portability swamp.  As a result, remove autoconf
check for <asm/atomic.h>.  Replace all this junk with
VKI_SIZEOF_STRUCT_MODULE (== 96) since that's all I ever wanted to
know in the first place.

- fixed a bug that was breaking the --threshold option.

vg_cachesim.c:
    - fixed a bug that meant instructions that didn't have a line number in the
      debug info were being written in cachegrind.out with whatever was the
      last known line number.  Now using 0.
