[Scons-users] Clone effectiveness

[Hua Yanghao]

Fully agree.

My approach is that I have a keyword parameter from the command line
to chose which target to build and then only the pattern-matched
builds are actually created, essentially only one env is created. I do
it only because I want to avoid the initial startup latency ... if
your env is not conditionally created or for a built that really have
many clones then bad luck. Of course it would definitely be great if
the we cannot feel the existence of scons's runtime.
