    I am familiar with the most kernel structures (actually i am digging
    with adb into crash files many times), but didn't find any appropriate.

    Application are 3rd party, all runs on a host itself. They're very
    complex (about 400-500 java processes).
    Most of the time i am successfull finding one (with truss -p <assume
    pid> and moving mouse over that window produce a massive
    lwp_mutexes...), but I am pretty sure XServer has that structure
    somewhere, if not in their temporary files, it must have some kernel
    process window tree...

    thx anyway
