It's not a known issue. I don't think that  would fix it because
that only affects new threads, whereas this issue is at least sometimes
about the main thread (the first thread created as part of the process)
The most valuable information for debugging here would be a backtrace of
the stuck thread. It's blocking for some reason and we don't know why.
