Re: bug #94 news

Which tells us a quite interesting story of what happened

1. The connection to the server failed, causing fwdStart to restart via a
dummy event (see fwdServerClosed). This is known by the fact that this is
the only case where fwdConnectStart is called via eventRun().

2. When the server connection was restarted in fwdConnectStart we picked
up a persistent connection. This can be told by having a straight
stacktrace fwdServerStart() -> fwdConnectDone(). In case of a new
connection it always goes via the comm_poll main loop.

3. And for some reason, the filedescriptor of this persistent connection
did not make out as a correct filedescriptor when http.c tried to send a
request onto it.

So a good measure would be to try to trap this error in fwdConnectStart().
If pconnPop returns a filedescriptor that does not make out as correct
then yell loudly and forget about it.. then try to identity why there is
"invalid" filedescriptors in the persistent connection heap/stack.
