I'm glad that I still haven't rebooted since then to get rid of the annoying situation and the observed anomaly still eats almost all of my CPU cycles, so here is the requested info.

First of all, I am unable to do successfully "(gdb) attach <PID>" as described in the wiki -- I get "no permission". Is it safe to run the gdb commands from the wiki as root?
