I might have come across the same problem, in my case I (on the windows
plattform, trying to port it to mono) show a splashscreen och process some
data in a separate thread, the system hangs with this call-stack when
invoking (from the processing thread to splash-thread) a set text method to
the splashscreen form:

    ManualResetEvent.WaitOne  <------ this one never ends and my app. hangs
