I use flock for this type of locking and it always worked like a dream for me.

Update: What I meant to say is that I use flock on the file itself to be locked, not on a separate lock file - it doesn't quite work like that.

I have done what you are doing on occasion, but in that case I opened the lock file '+<', did the flock and then a seek 0 and (over-) wrote the pid for testing, though I left that in there for support purposes.
