No, CVS originally read the file into memory using normal I/O.  It was
changed to use mmap instead, where available, in 1.11.2.  Then in
1.11.23 it was enhanced to fall back to normal I/O if mmap fails.  The
fallback code is also checked in to the 1.12 branch, but there hasn't
been a release that includes it yet.
