as far as I know, there is no parallel processing done while reading the 
SConstructs/SConscripts (=Execute() of your commands). So your best bet 
for decently parallelising things is to:

- wrap your commands up into a Tool/Builder (see 
http://www.scons.org/wiki/ToolsForFools ),
- get your dependencies right, and
- let SCons handle the rest. ;)

If you need help with one of the above steps, let us know please.

Best regards,

Dirk
