i tried this, setting it to 32768 as he recommended, then adding my archive
sources from the beginning of the year (i had been working with just
messages from the past month).  it caused a lot of exceptions in sup and
some segmentation faults in ruby.  i tried resetting the limit to 1024, and
got the exception below.

i think i'll have to assume sup/ferret can't handle many sources and change
my archiving system to accommodate.

I'm very sorry, but it seems that an error occurred in Sup.
Please accept my sincere apologies. If you don't mind, please
send the backtrace below and a brief report of the circumstances
to sup-talk at rubyforge dot orgs so that I might address this
problem. Thank you!

Sincerely,
William
