New description:
On many occasions, I find that an unattended mutt (1.5.17+20080114-1+b1
from Debian) will hang indefinitely. Never having time to debug it, I
usually kill it and restart it, but today I let it run in strace until it
happend. Here's what the end of the strace looks like - it seems to get an
ERESTARTSYS while reading from the imaps socket! ERESTARTSYS is reserved
as a signal between drivers and the kernel signal handling code and is,
theoretically, never supposed to make it to userspace. Thus, this is quite
odd.
I'm happy to add ltraces or whatever else may be useful....
