The cbus hang test uses glibc pthread mutex implementation details
(internal fields of mutex).
Comment from code of cbus_hang test:
" We want to cancel canceled thread in the moment of cpipe_flush_cb
will be processing.
A Linux specific dirty hack will be used for reproduce the bug.
We need to synchronize the main thread and the canceled worker thread.
So, do it using the endpoint's mutex internal field(__data.__lock)."
"A Linux specific" - a glibc specific.
