Hmm... I don't get it. Isn't the database version saved in the database? Why 
do we need to search the pkg-config file (which is a development file!) to find 
out how to use the database?

If this is required, it sounds like shared-mime-info is broken and should be 
fixed instead. I never got why we needed to run a subprocess in the first place.

In the meantime, I've been discussing with Rémi about the issue and he's not 
budging from his position that libraries shoul
 never use Unix signals. To be 
honest, he's right: Unix signals are meant to be used centrally only. But we 
need SIGCHLD to be notified that a child exited, so we need a compromise 
between apps and libraries.
