The changes definitely improve, as far as my impression goes. There was only
one notable pause around
r50651, and it is probably because the rather large "Checking svn:mergeinfo
changes since r15413"
from r15413? That took about 12 minutes. Other instances of "W:svn cherry-pick
ignored"
though do take a while, are in the seconds region - before the code changes
they could
be minutes, if memory serves.

I had to suspend somewhat around r59000 - but it is interesting to see
that the max memory consumption of the later part is almost double?
and it also runs at 100% rather than 60% overall; I don't know what
to make of that - probably just smaller changes versus
larger ones, or different time of day and network loads (yes,
I guess it is just bandwidth-limited?, since the bulk of CPU time is in system
rather than user).
I am somwhat worry about the dramatic difference between the two .svn/.caches -
check_cherry_pick.yaml is 225MB in one and 73MB in the other, and also
_rev_list.yaml is opposite - 24MB vs 73MB. How do I reconcile that?
