[Scons-users] Build goes into one thread, while -j8 set

[Непомнящий Евгений]

Hello!

I have scons 2.1.0 and scons 2.5.0

If I run
scons-2.1.0 -j8
, I see 8 compiler threads in windows task manager. But If I run
scons-2.5.0 -j8
, I see only 1 compiler thread. There is no warnings or something strange  
in scons output.

Project is my own and SConscruct is big and complex, it use my own tools
and other sconscript files.

Can you point me, what can be wrong? Or what debug info can I receive from
scons?

Windows 7 x64, python 2.7 x32 with pywin32.

Thank you
