I went back to read this posting again, and I noticed what you
said about the progress indicator stopping.  Mine doesn't stop.
It slows way up, but it doesn't stop.

This operation of getting headers, and I suppose sorting them,
apparently requires a lot of computation.  The newsreader I used
before Pan, rn, just bogged down completely when there were much
over 10,000 new headers.  I could give it several days, and rn
still couldn't finish.  Eventually, it would use all my ram and
paralyze my system.  That's why I switched to Pan.  So there
is nothing extraordinary about Pan getting really really busy and
taking a long time loading large numbers of headers.  Compared to
rn it does a great job.  But it shouldn't block the GUI.

I don't think Pan is hitting any ram limit on my system.  ulimit -a
gives max memory size and virtual memory as unlimited, and my GKrellm
monitor says my memory is only half used.
