Subprocessing. Why it won't be truly crossplatfrom

Every language and application stops to be crossplatform when it comes to executing other applications. Differences in a way various operating systems execute applications is so inconvenient that even new Python Subprocess API is not complete to keep you isolated from them.

Suppose you have an executable script.py in current directory that you want to execute. You would definitely need to execute the script through shell, because only shell knows which program should process it.





So you still need to keep in mind that to execute script from current directory you need to prefix the script with ./ under POSIX.
