Well, *I'm* the maintainer of hg-fastimport, and I have done one
conversion using cvs2git (another of cvs2svn's personalities) and
hg-fastimport.  It worked, but it's slow and takes lots of memory.  If
you really want to make git look good, compare git-fast-import to hg
fastimport.  ;-(

Part of the problem is hg-fastimport's inefficient handling of blobs
(git-speak for "file contents") and part is that I recently overhauled
hg-fastimport to use the 'convert' extension as its backend, and
'convert' keeps too much stuff in memory (so that it can toposort the
changesets).

Anyways... it might work for small/simple CVS repositories right now,
but those are the kind of repos that "hg convert" doesn't mind.
(Although it doesn't handle branches correctly in all cases.)  There
is lots of work to be done on hg-fastimport though.
