Comment 5 for bug 182923

To answer: the program is still responsive, I can open the preferences dialog and recheck mail by clicking on the blinking icon (depending on the settings). Oddly enough, I can only replicate the problem when I have three different types of mailboxes to check: POP3, IMAP and GMail. If there are only two, or, say a POP3 and two GMail, the CPU usage remains normal.

I've attached the output from using "-i", (I've altered my email addresses, though, for privacy).
