--- Comment #1 from Brooks Davis <brooks at FreeBSD.org> ---
In CheriBSD's cheri-purecap-kernel branch
(https://github.com/CTSRD-CHERI/cheribsd/tree/cheri-purecap-kernel) we have a
modification that reduces this to a single pointer to a structure holding the
other pointers.  In our case this is because the in-kernel use includes too
many pointers to fit when you blow them up to 128-bit.  This doesn't address
the leakage issues, but might be a place to start from.
