Are you saying that the fix didn't solve the problem for you? I
definitely saw a lot of GC messages after the fix where I didn't
before. For example, if you visit xdisp.c from the Emacs sources and
page through it with C-v, don't you see a lot of GC messages?

After a lot of consing, the GC would come back for a while, until it
would be effectively disabled again by some opportune code path.
If you see no GC messages for a long time, attach a debugger and look
at the value of consing_until_gc. If its value is huge, around
LONG_MAX, the problem is still not completely solved.
