> I'm porting what [~biilmann] reported in https://github.com/apache/trafficserver/pull/570 here:
> This pull request also seems to break one of our plugins that does HTTP requests in a background worker thread via TSFetchUrl (used indirectly through the AsyncHttpFetch C++ API).
> The HTTP request will hang at this check for the right thread and never progress:
> https://github.com/apache/trafficserver/pull/570/files#diff-40fc32ab3504372e0eb74a54108d1b6fR2404
> Removing these checks for the right thread leads to a segfault.
