yum memory consumption madness

[Paul Witt]

Hi,

Is yum well known for growing to very large memory sizes?  I just
ran 

  # yum whatprovides usbview

and the resulting process grew steadily in size until it reached
188MB resident size.  While it was growing it was also consuming
99% CPU.  Upon reaching its peak at 188MB, its memory usage dropped
dramatically and so did its CPU usage.  It's now a couple of hours
on, and the command hasn't returned!

This is on a system with 320MB RAM and about 600MB swap.

  Paul.
