 The segfault in GetExecutingAssembly() was likely fixed by r72369 (an
 issue introduced in r72349).
 Apart from the timeout domain unload warnings, the only other issue
 seems to be the double free reported in one of the traces (it is
 possible the locking patch fixed this, let us know if you see that again).
 Changing priority accordingly.
