Hi Michael, Thank you for the explanation! Thanks!

Note that ThinLock.inlineLock and ThinLock.inlineUnlock don't increment ThinLock.fastLocks, so the count won't be accurate if calls to ThinLock.inlineLock and ThinLock.inlineUnlock are inserted, which the opt compiler does by default.

Is this provided by Jikes too, I mean, is there any options in Jikes provide the information such as how many locks happen during the run? I know we can get this information with counter implementation in RVMthread, but just want to know is there any convenient ways to get this information. Thanks!
