Description of problem:
A typical scenario is when you run mutt with remote IMAP via VPN and the
connection terminates while mutt performs read from the IMAP server. The result
is that mutt simply hangs with no possibility of interrupting it with ^C and
there dooesn't seem to be any timeout so that mutt hangs forever. The only way
is to kill mutt, which then leaves a handful of temporary files in /tmp.

Version-Release number of selected component (if applicable):
mutt-1.5.18-1.fc10.x86_64

How reproducible:
always

Steps to Reproduce:
1. run mutt with remote imap via vpnc
2. change to a non-empty folder
3. kill vpnc so that the connection is reset
  
Actual results:
mutt hangs forever

Expected results:
mutt times out/displays error, is usable after vpnc recovery.
