When user threads are hidden, process now shows the
sum of processor usage for all processors. When user
threads are displayed, each thread shows its own
processor usage, including the root thread.
(thanks to Bert Wesarg for the report)
Also, add option to display thread colors differently.
disable useless code in release builds such as runtime type-checking on
dynamic data structures and process fields that are not being computed,
faster(?) method for verifying the process owner (still need to ensure
correctness), don't destroy and create process objects for hidden kernel
threads over and over. Phew. I shouldn't be doing all this today, but I
could not resist.
