increase performance of background parser

[Gerhard Stengel]

Hi,

I'm working with a quite big project which the kdevelop background parser 
needs almost an hour to scan each time I open it. The CPU load stays quite low 
(< 30%) as you would expect for a job running in the background, but I'd wish 
to cut down the time a bit. My computer's CPU has 8 cores, so even if the 
parser consumed more resources, there'd be enough left. I've already increased 
to 8 threads.
Would it be possible to add some feature in the settings dialogue to increase 
the resources the parsing may take?

regards

Gerhard
