Is it possible to disable pipelining in imapc?

Hi,

I've a broken IMAP server, which doesn't support pipelining and fails on dovecot's attempt to do this ([C] is dovecot's imapc, [S] is the IMAP server):

[C] 24 LOGIN "user" "pass" [S] 23 OK [C] 25 SELECT "INBOX" [C] 23 UID FETCH 2 (INTERNALDATE) [S] 25 OK [S] 23 BAD No mailbox selected

Sadly, fixing the server would be a hard task, turning off pipelining in dovecot's imapc (which already supports many workarounds for different servers) could be easy...

... except I can see no place to do this in imapc (only in pop3c and imap proxy, which I guess doesn't apply here).

If I'm right, may I ask for a knob for such dumb servers?

Thanks,
