If you can't kill a process with "kill -9 <pid>" then there is a
kernel/driver problem somewhere. Possibly triggered by the process but it
is not the process that is at fault.

However, I have never seen processes get stuck in 'R' (Running). A process
in state 'R' is supposed to be killable. Are you sure it was 'R' and not
'D'?

If it really is true that you cannot kill squid, not even with kill -9
<pid>, then upgrading probably won't help from this problem. But it may
save you from a number of other Squid problems.

It is a very good idea. Actually I have even made a patch to
Squid-2.2.STABLE3 once in a time but without an on/off option. (see
http://squid.sourceforge.net/hno/patches-devel.html#wait).

It is reasonable.

Implementation is fairly trivial.
