 I am experiencing this as well with varnish 2.0.5.

 It's not happening all the time, though. Sometimes, varnishtop runs fine
 until I quit. But other times it freezes after zero or one updates (either
 nothing happens, or I get one update. I have not gotten more than one
 update when this happens), using 100% CPU. It has to be kill(1)ed, after
 which the terminal needs to be reset in order to echo properly (which may
 suggest that some screen-updating-loop is running indefinitely for some
 reason, leaving the terminal in a weird state when killed).

 It seems pretty random. I have experienced several freezes in a row, or
 none for several runs and everything in between.

 A race, perhaps?

 I am running this on Linux 2.6.18-6-vserver-amd64 (it's a virtual server,
 yes, running on a Debian physical amd64).
