Tests: handled early pidfile write on win32 in the run() routine.
In addition to the present waiting for pidfile, which is insufficient on win32
due to the CreateProcess model, and may lead to rare startup races, search now
for the certain error message which indicates started worker process.
This change allows tolerating moderate hiccups on win32 hosts.
