Call to undefined function sem_get()

Given the trouble I was having with sessions I thought I'd try to roll my own. But I need a semaphore to stop multiple http requests geting in each others way. However when I try this is get the above error.
Do I need to do something special to use semaphones be used in this hosting environment, or are they unavailable?

Thanks Mook. Is compiling PHP something we can do from within the plusnet hosting environment? I assumed it was a shared environment and we couldn't do stuff like that.

TBH I am not the person to ask, but I seriously doubt it, but you never know. But I am sure others will clarify but you may need to wait until morning till a member of the PN staff is available.

A single PHP binary is provided by Hostopia to be shared by all users of the Plusnet cgi cluster. We aren't able to compile our own.
As far as I can tell semaphore support has not been compiled into our copy so associated functions will not be available.
