kppp leaks?

I have experienced what appear to be severe memory leaks from kppp in 
RH9.  I initially ran Gnome as my desktop, and was not able to leave 
kppp running for very long before it was using 50M or more of memory.  I 
had 5 hour session limits with my ISP - I now have 4 hour limits, so I 
would leave kppp running and simply re-connect as required.

After switching to KDE, the situation seemed to improve, but there is 
still leakage, and kppp is a memory hog anyway.  When I do a top sorting 
by memory usage, kppp starts near the top of the list.  This seems 
ridiculous.  What experiences do others have with kppp?  Is there any 
equally convenient alternative?
