Subject: Try again (up to ten times) if main loop exits prematurely.
X-Git-Tag: CPAN-v1.02~660
X-Git-Url: http://lists.indexdata.com/cgi-bin?a=commitdiff_plain;h=b3054bdd6afae46b4e5a7aae904ea3b4adff821a;p=irspy-moved-to-github.git

Try again (up to ten times) if main loop exits prematurely.
(Doesn't help in the current LoC failure case, but adds robustness).
Clarify logging.
