[Scons-dev] Subprocess.popen() on win32?

[Jason Kenny]

Been using popen with parts via overriding SPAWN var since the start.

+1 on having this be the default

Come now.
Win32.py's spawn implementation was updated in 2012.. ;)

If we universally switch to subprocess.Popen(), then we can safely chdir for non python function actions.
But passing in the cwd argument.

That seems likely to be useful..

Perhaps no-one has bothered to update that bit of code in the last decade and

Did you mean subprocess.Popen? Worth noting that the API for subprocess
changes from call* in earlier versions to run in later. Somewhat annoying for
compatibility across many Python versions.
