    Description

      In os_linux.cpp there are two ways to work with semaphores. The first uses the PosixSemaphore class, the other calls sem_post and sem_wait directly. It would probably be worth unfying these usages.

      os_linux.cpp:
      // Linux(POSIX) specific hand shaking semaphore.
      static sem_t sig_sem;
      static PosixSemaphore sr_semaphore;

      The same goes for os_solaris.cpp and os_bsd.cpp.
