[OGo-Users] graceful failure on absence of imap server?

[users@opengroupware.org]

Hi

I noticed whilst investigating backup strategies for Cyrus that if the 
imap service is stopped and someone is using the email components of the 
web ui, that ogo-webui will go into a cpu intensive spin.  Is this to be 
expected?  I understand that one might say that backups should not be 
taken whilst there are users online.  But I'm more concerned that the 
other aspects of the web-ui should become unresponsive if the imap back 
end went away for a short time.
