I'm sad to report, though, that tests of 0.2.1 still hang here.

I'm testing it with the following command:

  $ test-new-egg nng

I executed the command above three times and tests hanged consistently.

I'm using strace to verify that the test process is not actually doing

$ strace -p 14836
strace: Process 14836 attached
restart_syscall(<... resuming interrupted poll ...>

All the best.
