I see that on OS X, with its underperforming filesystem, but not on other platforms (my VM use is mainly on 64-bit FreeBSD). Giacomo’s on Linux, so that shouldn’t be it.

You should try reporting on the VM channels (M-x > report-vm-bug is the way to go, I think). It should be possible to set vm-flush-interval to nil; this will only sync in-memory changes using the normal autosave procedure and manual saves. This might be good enough for Giacomo.
