[Users] issues freezing claws during suspend

[Bob Jenkins]

Hi,

I've had issues doing ram->swap hibernate with my laptop.  Claws won't
freeze sometimes according to dmesg.  I thought it might be the wifi
disappearing when claws was in the middle of a connect attempt, but I set
'socket I/O timeout' to 10 seconds, with no joy.

Any suggestions?  Is there another "already connected, won't time out for
kernel /proc time on TCP connection" sort of claws thing?
