There's an idea, but since I work from home the machine is right
there, stalking me...

What might be a better idea than re-generating 1000 files worth of
symbols each time is to run offline tags file generation, hopefully
loading those will be faster than re-parsing all the files.  Maybe you
can test it some time.

And Geany will correct any errors in symbols for the files you have
open and have changed.

All we need to add is the ability to save this over the top of the old
tags file when the source file is saved, so you continue to get right
symbols with the file closed.  This is something that will be much
more likely to happen in the near future compared to threaded parsing,
there are too many problems with data sharing with the GUI thread, as
discussed several times on IRC in the past.

Depends how much faster loading tags files is to see if its worth it.
