Resolve thread sanitizer issues #98
Description
Reported in: 0.3.6
When Thread Sanitizer is enabled in Xcode, some warnings are posted to the console. This likely is a byproduct of the multi-threading that was introduced a little while ago (#49).
But in practice, the operation of the tool does not seem to be adversely affected (it works as expected). It's likely the warnings are being triggered by an over-abundance of caution from the TSAN but it would still be good to resolve them.
