this is the v4 release of the syslet/threadlet subsystem:

http://redhat.com/~mingo/syslet-patches/

v4 is a smaller update than v3 (so i wont send out the full queue to
lkml - see the broken out queue in the patches-v4 directory at the URL
above). Changes since v3:

- the threadlet API changed: the sys_async_threadlet() syscall now takes
a 'completion event' pointer, and auto-completes it into the
completion ring. I've updated the test-threadlet.c code to make use of
it. So completion of threadlets and syslets is quite similar now -
sharing even more infrastructure. (To get true pthread compatibility a
sys_exit() driven CLEARTID completion method will be added too in the
future).

- a small performance fix for syslet rescheduling. The syslet ABI has
not changed.

- test-threadlet.c fixes a thread stack leak, and the other tests too
have a number of small fixes and cleanups.
