Read some texts about locking in PHP.
They all, mainly, direct to http://php.net/manual/en/function.flock.php .

This page talks about opening a file on the hard-disk!!

Is it really so? I mean, this makes locking really expensive - it means each time I want to lock I'll have to access the hard-disk )=

Can anymore comfort me with a delightful news?

I'm using the C++ boost::thread library, which in my case means I'm using pthreads.
