Hi,
Apologies if the answer to this is someplace I have not looked. I've searched
this list and other sites/FAQ's.
I've noticed that command listed in the subject line always yields
<not counted> cycles
unless the target process is suspended. I have noticed this with a few different
distributions. Is the fact that the target process has to be suspended at least
once a known design limitation or would it be considered a bug?
Thank you for your help.
Chris
