Yeah, there is a command line utility that searches for wireless
access points and lists their respective signal strength etc.
(iwlist), and I only run it if I think an access point should be there
and I am not finding it or getting a poor connection.

It seems like networkmanager runs iwlist or does some equivalent on a
frequent basis (even if it already has a wifi connection), and uses
quite a bit of CPU doing it. I no longer need to worry about this
since switching to debian, where the /etc/network/interfaces config
file plus the ifup/ifdown commands that reference that configuration
have served me just fine.
