Excellent. Would be handy to see it explicitly in readme or copying files.

[LibOS] disable preempt on helper thread exit
9a69395 
When a helper thread exit voluntariy, the following segv happends.
The reason for segv is, __handle_signal() tries to access
shim_thread, it's already freed.
This situation only happens with helper threads. exit system call
doesn't trigger this pattern.
So add __disable_preempt() before put_thread() in helper function
as exeption.
