  Priority:  high            |  Milestone:  PostGIS 3.1.10

Comment (by pramsey):

 Wellll, in the short term we should comment out those callbacks, since
 crashes are worse than (minimal) missing interruptability. In the medium
 term, I am going to try to make an ASAN build of everything and see if I
 can induce some kind of out-of-bounds write by wagyu... my working
 hypothesis being that it does an out-of-bounds write on every interrupt,
 but only a very small fraction of them manage to overwrite something
 critical enough to cause a crash.
