I did this in /usr/src.
grep -r --mmap vmpfw *
sys/vm/vm_fault.c: if (!vm_page_sleep_if_busy(fs.m, TRUE, "vmpfw"))

Just above this line is a comment explaining what is happening here in a  
technical way.
I think your imap server is mapping all files in memory which can take  
quite long if your memory isn't 30GB.
Do you have more info about your system?
Memory/CPU/NFS?/local disk?
Are the mailboxes in mbox format or Maildir?

Searching in google on 'vmpfw' gives nfs issues with it while using pine  
on a nfs mounted mail folder. (results from 1999 about older versions  
freebsd)
