It would be nice to have some resolution on the large SPEC performance
degradation [https://sourceware.org/PR34394] caused by:

    malloc: Remove dynamic mmap/trim threshold [BZ #30769]

    v2: Update documentation

    Whenever a large mmap is released the mmap and trim thresholds are updated.
    As a result these thresholds grow ever larger which means huge allocations
    are always served by arenas rather than mmap.  The thresholds can end up as
    large as an arena, which completely stops all trimming of the top block.
    Remove the code completely - the default thresholds seem way too low for
    modern 64-bit targets, but they can be increased seperately.

...before the release goes out.  I'm not sure the best course of action though,
whether we can get a fix for that, or whether we should revert the problematical
commit for the release and try to fix it after?  Thoughts?
