offlineimap ignores SIGHUP, causes shutdown delays if left running

[Steve Langasek]

After noticing that my shutdown was much slower than it ought to be, I did some debugging with /etc/init.d/sendsigs to find that offlineimap hangs around well after the rest of my desktop has exited. This is because offlineimap installs a SIGHUP signal handler and keeps running after the terminal has exited, because it interprets SIGHUP as a signal to wake up the accounts.

Either this should be frontend-specific, or the handler should only be installed when not run from a tty, or the default signal handler should always be used for SIGHUP.
