[issue23253] Delay-load ShellExecute[AW] in os.startfile

[Steve Dower]

Steve Dower added the comment:

Attached a patch.

Comparing the time for "python.exe -c '0'" with Powershell's Measure-Command 
tool, it looks like there's a 3-4ms (~8-10%) improvement in startup time too. 
That's not at all robust, but it's certainly no worse. (I'm not surprised - 
shell32.dll is a horrendously big dependency and we're better off without it.)

[issue23253] Delay-load ShellExecute[AW] in os.startfile

[Steve Dower]

New submission from Steve Dower:

Currently, pythonXY.dll has a dependency on shell32.dll solely for the 
os.startfile (Modules/posixmodule.c) function. This is quite a heavy dependency 
that many would rather not have to load (e.g. lightweight server 
configurations).

It would be nice to delay load the DLL and fail the operation if it is not 
available.

(This is as much a reminder for myself as anything else, but if someone wants 
to do it then feel free.)
