I took a fresh copy of the database from the server. The problem  
completely disappears with that new db file (!?).
It's still happening on the other file. I'm pretty sure the db is ok  
(monotone wise); db check returns fine.

Suppose there would be the possibility of a stale lock file (not sure  
if sqlite/osx even does that, reading through os_unix.c in sqlite  
doesnt bring much optimism to the table either), could that be a cause?

From running fs_usage on the mt process it just displays a read/ 
lseek during the whole time mt sits doing nothing. fs_usage also  
displays a 'W' in its output (from Waiting?) but i havent been able  
to figure out what that means.

Although the new db copy workaround seems to solve my direct problem,  
i'm now too deep into it to give up and really would like to know  
what's causing this.
