Then tell UW-IMAP to stop broadcasting the entire home directory of  
the user as part of the namespace.  This is what has changed in IMP  
4.1 and is clearly described in imp/docs/UPGRADING.  If you are  
unable/unwilling to fix UW-IMAP, then you should continue using IMP  
4.0.x.

I can verify that a correctly configured IMP 4.1.x installation is  
*much* faster than a correctly configured IMP 4.0.x installation - in  
terms of both PHP execution time and reduced number of calls to the  
IMAP server.
