Subject: Catch all ZOOM::event() return values less than 1.  This includes -4
X-Git-Tag: CPAN-v1.02~608
X-Git-Url: http://git.indexdata.com/?a=commitdiff_plain;h=5afbaa12a9aef6bde35819ab312e0e2a8081905f;hp=5afbaa12a9aef6bde35819ab312e0e2a8081905f;p=irspy-moved-to-github.git

Catch all ZOOM::event() return values less than 1.  This includes -4
	(too many connections), which was the cause of the busy-loop
	failure when testing all targets.
Final play-out of left-over events also avoids busy looping on
	unexpected negative return-value.
Do not re-enter main loop after initial exit.
