It will, as of now, the thread is doing busy looping and thus will be
scheduled. If it can be put to sleep, the thread will not be scheduled.
It is quite easy to check with task manager on windows or top on linux. 
I am quite convinced you will see merkaartor using up all available
cpu time (or 50% on a dual core) when serial gps is running.

Well, on the N810 gpsd is started by default and is the documented way
to access the GPS. Not sure why Maemo choose to work with gpsd though.
Maybe because it allows easy sharing of that single device?
