That's what I meant by "unsafe". I'm still wrapping my head around
this stuff, so apologies if I ask stupid questions. Here's another
one: why accessing the same object's memory that may be protected by a
barrier OK from the main (a.k.a. "Lisp") thread, when MPS could have
meanwhile started GC asynchronously? IOW, how is this "normal" access
to Lisp objects different from access from a signal handler?
