Firstly the disclaimer, this advice comes with no understanding of the
FM API, but rather general OS X programming (well, Cocoa
specifically). It would probably be worth trying to find out if the FM
API is thread safe or not, someone else on this list might be able to
comment on that.
If you're using NSNotification I'm guessing you're writing the daemon
using objective-c and Cocoa, so I'd suggest you look at creating
another thread (using NSThread) and do your processing in there.
Assuming you're not going to be receiving these notifications with a
high frequency (e.g. consistently high numbers per second) the cost of
creating and tearing down an NSThread instance for each NSNotification
you receive shouldn't be too high. If not creating a pool of worker
threads would be more efficient (but a lot more work as well).
Hope this helps.
