Our file locking model should be 100% posix bogon compliant. Because
this causes performance problems for sane software we actively
discussed including a facility to break that compliance at OLS, but
not to remove it as the default.
POSIX threads requires that file locks be per process, and not
per-thread. The fact that we treat threads === process causes problems,
no?
(I'm not arguing whether or not the Posix model is bogus or not; I'm
just stating that I think there's an incompatibility here.)
