Re: git-svn metadata commands performance issue

Huh.  I thought with the advent of demand-paging, at the very least with
copy-on-write, this was supposed to be sort of a non-issue.

The old original UNIX version, in contrast, consisted of swapping out
the current process without removing the in-memory copy.  But since the
in-memory copy then did the exec call and since usually the exec call
was happy about every page of free memory (we _are_ talking about
something like 64kB of total available memory here), that tended to work
reasonably well.
