pubsub test freezes when built with libevent 2.1.x

[jollyroger]

Hi,

Debian is underdoing migration to libevent 2.1.x. With this library running pubsub test takes forever (progress stops on 2%):

make[2]: Entering directory '/build/webdis-0.1.4+dfsg'
python tests/basic.py
......................

python tests/limits.py

./tests/pubsub -p 39805

E: Build killed with signal TERM after 150 minutes of inactivity

I have tested both webdis and pubsub binaries compiled with old and new libevent library and found that the issue lies in the pubsub test rather than in webdis (the webdis binary compiled with libevent 2.1.x works fine with pubsub binary compiled with old libevent library). Unfortunately I'm not familiar neither with libevent nor with programming in C to fix this.
