Okay, this makes things more clear to me.

Having a look at various source files makes me believe that the
problem described has something to do with memory access of Opera
"through" the kernel (mutex -> mtx). It furthermore explains the
"hanging" - a sleep command in the kernel.
For the "uncond" state, I found nothing as informative as the
above. Maybe it's a "don't know" placeholder. :-)
PID USERNAME THR PRI NICE SIZE RES STATE TIME WCPU COMMAND
9774 poly 3 101 0 145M 115M ucond 0:00 11.08% opera
Furthermore, I think top(1) gets the text for the locks from
somewhere else, they're not part of the top(1) sources. At
least, /usr/src/usr.bin/top is very dry and doesn't contain
much more when in /usr/obj. :-)
