Hi,
Valgrind still seems troubled when it comes to multithreaded
programs. It seems pthread_self() always returns the same id no matter
which thread calls it - possibly the id of last created thread. Running
a simple test program under Valgrind fails whereas running it as a
regular binary works fine.
No matter how you twist and turn the creation of mutex'es they seem
to always end up recursive, and don't really protect anything as thay
can be taken by multiple threads simultaneously. They also seem to
behave differently depending on whether they were initialized
dynamically - as in using pthread_mutex_init() - or statically as in
using PTHREAD_MUTEX_INITIALIZER.
