I downgraded to KDE 4.13.3, and removed,recreated the gmail account. The issue
has become much less frequent. Here's some output from netstat:

With the "too many simultaneous connections, enterpassword/try again/cancel"
alert still open:

> netstat -aeepW | fgrep imap
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)

unix  3      [ ]         STREAM     CONNECTED     5392192  18352/akonadi_imap_ 

After hitting cancel, causing kmail to take the account offline:

netstat -aeepW | fgrep imap
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp        0      0 patux:57526             wi-in-f109.1e100.net:imaps

unix  3      [ ]         STREAM     CONNECTED     5392357  18352/akonadi_imap_ 
unix  3      [ ]         STREAM     CONNECTED     5392742  18352/akonadi_imap_ 
unix  3      [ ]         STREAM     CONNECTED     5392270  18352/akonadi_imap_ 
unix  3      [ ]         STREAM     CONNECTED     5392192  18352/akonadi_imap_ 

In other words, taking the account offline does not cause it to close all its
connections to the server, something I'd expect.

Sending a SIGHUP to 18352 causes it to exit, and immediately thereafter I can
online the account in kmail with success.That would appear to offer at least a
suggestion for a workaround solution. The restart command in the akonadiconsole
does NOT have that effect (in fact, it rarely appears to do anything with imap
accounts ... unless they're working properly?!) but it'd be much more
convenient NOT to have to launch a separate application to correct an issue
that's apparent in kmail.
