Did you use progress points?
This should have been at least partially addressed in libelfin with this commit: https://github.com/aclements/libelfin/commit/74f11163334653866c08c32430bbad33c1a7877f
See https://github.com/aclements/libelfin/pull/41
Hi @ManuelMeraz - would you mind submitting a PR to fix this?
Ping @ccurtsinger
It's the holidays, but bumping this for @ccurtsinger
Another option might be for Coz to expose a mechanism that would let programmers indicate that certain functions correspond to `pthread_mutex_lock` and `pthread_mutex_unlock` and `condvar` friends.
Can you share the benchmark? Have you inserted any [progress points](https://github.com/plasma-umass/coz#profiling-modes)?
Just out of curiosity, have you also tried using it by installing it directly with `sudo apt-get install coz-profiler`?
