I was doing some benchmarking on tests on linux, and noticed that 10-20% of time was in ThreadCheckerImpl::CalledOnValidThread. I looked into it and found that we're doing a syscall to get the thread ID, which is not needed on any platform where pthread_t is already an integer type. Replacing that syscall with pthread_self() makes this particular test (End2EndTest.BasicFakeSoftwareVideo) go from 488ms to 374ms, which is a 20% speedup. While other tests might not use ThreadChecker quite as much, it should still be a pretty good win across a large set of tests.
