Are there any non-commercial tools that do similar things? I'm looking for a way to test a faster and smaller read-write lock implementation I'm playing with, but as it's a hobby project I can't afford to buy professional tools for it.

I'd be looking for something that would run on Linux. Open source would of course be nice, but free is probably more important to me in this case. Finished product will be open-source designed to replace pthread's rwlocks.
