anozdrin/alik@alik. d238bd6755 Patch for BUG#15934: im_daemon_life_cycle fails sporadically.
The problem was a race condition in a test case.

The fix eliminates the race condition by explicit
wait on UNIX socket to start accepting connections.

The patch affects only test suite (i.e. does not touch
server codebase).
