This seems to be the first Google hit for
 [mercurial delete old revisions]

http://stackoverflow.com/questions/3971961/removing-changesets-or-shrinking-a-mercurial-repository

The first answer is to create a new, unrelated, repository with only
some of the original revisions as follows:

hg -R /path/to/bigrepo export 5001:tip > latestchanges.patch
hg init newsmallrepo
hg -R newsmallrepo import < latestchanges.patch

Thanks,
Robert
