No worries.

It may not stay that way.  Many u-blox GPS ship with 9,600 bps and
that does not allow for a lot of data every second.  If this overloads
some users then it may have to change.

No matter what, the gpsd u-blox init has to get better.  Right now it
just shoves all the change requests at once, and not all are valid for
every u-blox, and may overload the input buffer.

The SiRFstar init is a bit better, it has to be because it overflows
input easier than the u-blox.  But neither is solid yet.
