I might also add another datapoint:

OS: Mac OSX Yosemite
offline installed via homwbrew

I have three servers (gmai, icloud and 1&1) which I sync to local imap
dovecot server, and after a suspend, in many cases, the gmail account
hangs, while the others are still working.

Passwords are extracted from OSX Keychain by using

| import re, commands
| def get_keychain_pass(account=None):
|     params = {
|         'security': '/usr/bin/security',
|         'command':  'find-generic-password',
|         'account':  account,
|     }
|     command = "%(security)s %(command)s -g -a %(account)s " % params
|     outtext = commands.getoutput(command)
|     return re.match(r'password: "(.*)"', outtext).group(1)

As this happens quite often, I will kill it the next time with the
SIGQUIT and send in the traceback.
