Re: how to handle connection to server if server runs away?

[David B. <d.b...@ma...>]

There seem to have been a few people interested in either reconnecting on
time-outs, or getting past search-limits...both of which are optionally
imposed by the server.  
Since it's clear that Graham et al think it shouldn't be part of the
library, rather a function of the application, does anyone who's done this
sort of thing have sample code that they'd like to share...perhaps it could
be added to the as-yet-nonexistant-but-hopefully-soon-going-to-be FAQ.??
