Semaphores without sysvmsg?

[Michael McGlothlin <michaelm@xxxxxxxxxxx>]

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,
