Subject: prevent erratic (multiple) changes of chan limit in short space of time.
X-Git-Url: https://git.donarmstrong.com/?a=commitdiff_plain;h=5fa33c4086e00c647d1b308c044cd10ca670290d;p=infobot.git

prevent erratic (multiple) changes of chan limit in short space of time.
this would be a major problem in chanlimitVerify@IrcHelpers.pl since
it's called for every join.  Better safe than sorry.
