Update to 6.1:

This is essentially minor bug-fix release, which most notably works
around "unable to anonymously mmap" failure at startup and fixes
typo in -speed interpretation code.  Besides bug-fixes this version
attempts to obtain exclusive lock on block device under Linux. This
opens possibility for safe deployment of automounting/autoplaying
facility under Linux 2.6. Keep in mind that it takes two to dance
tango, automounters/autoplayers has to play along as well.
