123362235b * use initc.fpgetCerrno rather than fpgeterrno to get the errno 
results of the sem_* routines (since those always come from libc/
    libpthread)

494fb81dd8 * fixed semaphore implementation based on file handles (select needs 
file descriptor + 1 as first parameter, select can also be EIntr)
  * changed IntbasiceventWaitFor (used by syncobjs) so it can emulate
    timeouts (using a loop and short sleeps) (mantis #9414)
  * also added wrAbandoned support to IntbasiceventWaitFor
  * enhanced tbrtlevt.pp to test new functionality

fd98a0cc5b * don't call runerror if a unix threading error occurs (because this 
immediately terminates the whole application), but instead call
    handleerrorframe (which can be converted into an exception) (#7954)

4dd3be0e5a * return thread function result via pthread_exit() from CBeginThread 
(Vinzent Hoefler)
  * simplified CWaitForThreadTerminate based on comments from Vinzent
    Hoefler
  * fixed resource leaks where in some cases a pthread would not be
    reaped based on comments from Vinzent Hoefler (resolves #9016)

0c3afc0cf4 + implementation of cSemaphore* and BasicRTLEvent based on 
sem_open/sem_close for Darwin (doesn't have sem_init/sem_destroy)
  + implementation of cSemaphore* based on pipes (for potential future
    systems that don't have either sem* routines)
  + test for basicrtlevent
  * fixed datarace whereby a TThread could be started, run and exit before
    TThread.AfterConstructor had been called (Mantis 6693, all platforms)
  * throw EThread exceptions in TThread.create if something during creating
    the tthread goes wrong (*nix)
  * don't crash in TThread.Destroy if the TThread throws an exception before
    it was fully initialised (*nix)
  * changed order of operations in TThread.Destroy so it doesn't perform
    invalid thread operations in some edge cases (*nix)
  * fixed usage of sem_wait/sem_trywait (can be interrupted) in Semaphore
    and RTLEvent implementations
  * fixed erroneous waiting for threads after they had already exited via
    pthread_detach/pthread_exit
  * fixed several memory leaks in case of thread intialisation errors
    (*nix)
  * unified tthread.inc for all Unices
