I cannot reproduce this. For me, everything is fine. When I reach the point
where ')' is the first symbol on the line, nothing freezes, and CPU usage
continues to be normal.

I have precisely the same.

maybe it is an interaction with some other emacs macros ? Can you try again
without loading into emacs anything else besides tuareg ?
