hesitant to put much code in an interrupt handler -- I
have always thought that has issues too.

Generally you don't care about an EINTR on a semop()
Ok, I tried to use semaphores between php and C++. Where the php script
was the client and the C++ app was a server. Client only acquired sems,
server only released.
This cannot be done with php semaphores. Got around the first two
problems:
1) Php semaphore is actually 3 sysV sems

Does anyone have a good method of supporting semaphores when PHP's
System V IPC functions can't be enabled? I'm trying to implement locking
for using shmop (actually modifying someone elses code) and it requires
sysvmsg but my shared host doesn't have this enabled.
Thanks,

I know there is no support for semaphores in Windows.
But does the Windows and Mac implement semaphores ? If they don't what is
used instead ?
Can PHP use this functionality on these OS like semaphores on *NIX ?
