fbd9d9f778 DO NOT UPDATE! COMPILES BUT DOESN'T WORK. 
Major overhaul to the way thread startup and exit is done.  Removes some
ugly gunk in the scheduler, and adds support for thread detaching and
cancellation.

8d2d128371 Don't mask libc's vfork / __vfork: 
$ nm /lib/libc-2.2.4.so | grep vfork
   000b4220 T __vfork
   000b4220 W vfork

There's no __libc_vfork, so there's nothing we can do here.
Just don't supply our own version.

Not at all sure if this is correct.

96b04d4f30 Fix fork/exec stuff so it works again. We have to mangle LD_LIBRARY_PATH 
as well as LD_PRELOAD, so as to make our libpthread.so go out of scope
when a child which we don't want to trace, is exec'd.  Otherwise the
child can wind up being connected to our libpthread.so but not to
valgrind.so, which is an unworkable combination; you have to be connected
to both or neither.
