Package: emacs
Version: 25.1.50

Current master on RHEL 7.2.
Sometimes network-stream-tests hang "forever" (I killed it after 10
minutes of nothing happening).

A similar hang is visible on hydra several times, eg
http://hydra.nixos.org/build/35810871 (it tried 3 times, once it aborted
after 2 hours, from watching the log as it was happening I know it was
in network-stream-tests).

My network-stream-tests.log file says (only):

    Running 10 tests (2016-05-16 17:36:18-0700)
    gnutls-serv: Set static Diffie-Hellman parameters, consider --dhparams.
    HTTP Server listening on IPv4 0.0.0.0 port 44331...bind() failed: Address already in use
    HTTP Server listening on IPv6 :: port 44331...bind() failed: Address already in use

Whee, just found another one of those in my process listing - running
for 23 days and counting. :)
Emacs should probably be more robust about killing those off...

PS but it will still hang even if no stray gnutls-serv processes are
running before "make check" is called. In that case the log file says:
    
    Running 10 tests (2016-05-16 17:54:45-0700)
