It's used by core module IPC::Open3 (and Open2) instead of fork+exec when used on Windows.

What the advantage of doing this instead of using fork? | [reply] |
Why bother cloning an entire process if the next thing you are going to do is overwrite it by loading another program?
The system 1, 'other.exe' only works on Win32. Win32 does not have the concept of forking in the OS, and Perl's fork is an emulation of that concept implemented using a thread. Unfortunately, the emulation does not quite live upto the functionality of *nix fork.
