(win32_wait): Use EnterCS/LeaveCS for the critical section. Properly
copy the PID list locally to ensure that even if the list is updated
the local copy remains valid. Add into the hl (handle list) the
ProcListEvt handle. This handle is used to signal that a change has
been made into the process chain list. This is to ensure that a waiting
call can be resumed to take into account new processes. We also make
sure that if the handle was not found into the list we start over
the wait call. Indeed another concurrent call to win32_wait()
could already have handled this process.
