[PyKDE] [PATCH] threaded build.py for PyQt 3.6

[Hans-Peter Jansen]

Hi Phil,

with the attached patch, build.py is able to saturate multiple CPUs on 
module code and Makefile generation. Since we're running out of command 
line switches, it's triggered by a -j# option from the MAKEFLAGS 
environment variable.

Downsides: 
- on a sufficiently fast SMP system (dual Athlon MP 1700+), it's 
necessary to refine the make call a bit, in order to get the qt module
build first, since all other modules depend on it, aka:
cd qt && make && cd .. && make
- KeyboardInterrupt doesn't kill the build.py process reliable while 
threads are running.

If you're going to accept this patch, I will update the docs 
accordingly.

Would you accept a patch allowing to build sip and PyQt into an 
independant path like I've done it for PyKDE before? 

Pete
