Not in my tests yesterday.

One thing I noticed as well -- in the last days it stopped writing to
track-ALL.sav and left behind a file called incremental.sav. Is this
a new bug introduced by the new Really-Clear prompt? commit or some
local mistake by me? (gpsdrive left running for 10 hrs)

And, fwiw, by using gpsbabel's built in gpsdrive filter .sav can be
converted into GPX format. (also merged, downsampled, filtered, ....)

ah.

but how is that better than losing all your day's data? I'd rather
have slightly broken data than zero data. I can fix broken data.

coupled with memory flush -- in permanent installs you may want to have
gpsdrive running for a week+.
