Ian Rogers f92993851f perf bench: Use condition variables in numa. 
The existing approach to synchronization between threads in the numa
benchmark is unbalanced mutexes.

This synchronization causes thread sanitizer to warn of locks being
taken twice on a thread without an unlock, as well as unlocks with no
corresponding locks.

This change replaces the synchronization with more regular condition
variables.

While this fixes one class of thread sanitizer warnings, there still
remain warnings of data races due to threads reading and writing shared
memory without any atomics.

  Basic run on a non-NUMA machine.
