--- Comment #27 from Kevin Puetz <PuetzKevinA at JohnDeere.com> ---
To make debugging harder, once that least thread has exited (the starting point
of this use-after-free), the process is now racing a timer started in
wineserver's process_killed that will SIGKILL the process in 0.5s, preventing
one from really stepping through any of this (since even an attached debugger
can't block SIGKILL)
