I observe the delays and apparent freezes both in Fedora and in Windows-7. I observe them
with non-gmail messages/folders, even drafts. I'm using imap. These suggest that the
problem is not with Fedora, but one or more of:
* Thunderbird code that is not OS-specific, and not mail service specific,
* mail service servers (agreeing with Tim), or
* network delays (agreeing with Tim).
