OpenMP and OSX 10.5

Anyone know if OpenMP is broken in 10.5? I have some simple code that I optimized and parallelized with OpenMP but when I run it takes way longer to finish compared to serial.

I've read some reports of thread scheduling issues with OpenMP on OSX, but they were at least 1 year old.

Anyone else have these issues or heard of them?
