(1) it used to go ahead with regression even when *.reg file does not exist (and regression always ends up failing)
(2) when WORKERNAME env variable isn't set, it creates "time" instead of "time.reg" (presumably because count << "time_" << host << ".reg" fails halfway when you do << host, and ".reg" is not appended as a result)
