We do have timeouts, and use async APIs where possible.  Evidently, it
somehow doesn't work in your case.  But you didn't give enough
information to start digging into the problem.  Assuming this is
reproducible, please attach a debugger to Emacs when it hangs like
that and show the C-level backtrace.  Please report the results as a
bug, using report-emacs-bug, which will also collect several important
aspects of your build and setup.

Armed with that knowledge, we might be able to investigate this
problem.

Thanks.
