IMAP connections run in separate threads with different sockets, no way they
can interrupt another open connection AFAIK.

The network log is a shared resource and messages from different protocols or
sessions may be mixed, but that doesn't mean connections to the servers are
shared.

In fact your log shows a clear example of a POP account which also timeouts
without any other message in between:

,-----
| * Account 'uk-drills-non-delivery': Connecting to POP3 server:
94.76.203.118:110...
| ** Session timed out. You may be able to recover by increasing the timeout
value in Preferences/Other/Miscellaneous.
`-----

So, I think that the POP server was simply having connectivity problems at
wrong moment.
