Expect Linux has similar but FreeBSD has per-process limits on  
memory. Default is 512MB. So unless one has a number of processes  
drawing 512MB having 3GB doesn't do a single application much good.  
However the OS will use the extra for disk caching.

When all of the headers from a group have been downloaded pan spends  
some time doing housekeeping at the expense of GUI updates. Guess its  
reconciling the list against the list stored on disk, and saving to  
disk. When the GUI freezes I notice about 8 MB/sec of disk activity.
