Well, of course I want to keep it - but I am biased :)

I think its a simple export that gives us a neat feature. Additionally,
from the procps perspective, it saves us from having to parse
for each process. In fact, it means we do not need a at all
for any procps functionality.

I guess Linus at least mildly liked it too, since he merged it.

But if its such a performance crippling item perhaps it does need to be
removed (or somehow restricted).

I do agree that, if possible, wchan should be kept simple... so, is
everyone else for the removal of /proc/pid/wchan ? :-(
