fitzgen opened PR #13422 from fitzgen:wasmtime-drc-over-approx-force-gc to bytecodealliance:main:

This should trigger collection in more situations than just filling up the heap from allocation.

Fixes https://github.com/bytecodealliance/wasmtime/issues/13403 in theory, but I haven't been able to measure sweep times reported in that issue without this fix on my laptop. FWIW, that issue does refer to Android, and so is probably using radically different hardware.

Comment here why this can't overflow? (Presumably because we'd run out of memory long before?)
