There was a problem hiding this comment.
I think it would make more sense for this to be declared after queries so that we store null before the destructor of GlobalCtxt gains unique access, even though it offers no synchronization.

Doesn't work yet, because we try to share a
Compileracross thread boundaries, which mostly doesn't work because some things likeFreezeLockare notSync, but onlyDynSync.intended as a replacement for #115220
cc @Zoxc do you think this is doable once we nuke the non-parallel-compiler cfgs and do some cleanups by using the thread safe sync primitives everywhere?
