I was able to fix this problem by using this commit version a299e7f. As it has a change that uses a mutex to stop common reads.
But it doesn't seem like it is available in the latest release tag.
@adam-cv You're absolutely right, I should push a new release asap.
Should you still be able to reproduce this with v0.2, please let me know here.
