[Scons-users] Errors in parallel builds after updating from SCons 2.3.0 -> 2.3.5

[mg at ncp-e.com]

I can do the hg bisect if it becomes necessary.

But I think the problem is actually on my side of the code and that it
was just coincidence that it worked in the older versions of SCons.

The thing is that I've got a Command builder and when the builder runs
it adds new Install() instructions to the environment. Is this even
supported by SCons?

The error when building with multiple jobs always comes from this spot.
