[Scons-dev] Subprocess issue on Linux?

[Kenny, Jason L]

I think yes, in that it does what should be done by the system under posix_spawn.. ie call vfork and execve.

Here is the last version of the monkey patch I have from the people working on it. It has a fallback to the classic fork exec if the API's don't exists. It seems to solve the main speed problem for us at the moment. I believe it still being tested to find possible issues.

Hi dirk,

While I don't have a patch to SCons at the moment we have people in my team fixing this with Parts as a monkey path to sub process module. I asked the two people working on this to speak up and update their patch work online for SCons to consider.

Jason, do you have a way to do posix_spawn from python (without a C extension)?
