Note that in the original "ps" output, it's clearly a list of separate
processes. "ps am" output would make that clear (threads show up with
"-" for a pid). And the original poster didn't do that (nor "ps H").
Don't think there's any way to hack $PS_PERSONALITY to get such
behaviour invisibly, either.

Any chance, Hong Yuan, that slon could (and had reason to listen to)
make use of network paths to other boxes that it didn't have before?
Is this condition continuing? Care to do a "ps -Haf | egrep slon" ?
