I'm starting to use Helgrind a tool of Valgrind. I read on the manual the 
following statement:
Runtime support library for GNU OpenMP (part of GCC), at least for GCC versions 4.2 and 
4.3. The GNU OpenMP runtime library (libgomp.so) constructs its own synchronisation 
primitives using combinations of atomic memory instructions and the futex syscall, which 
causes total chaos since in Helgrind since it cannot "see" those.

In the latest version of GCC, is this still true or now the OpenMP uses the 
standard POSIX pthread?


Do you have a specific OS family in mind?
