On win32 threads share STDIN/STDOUT/STDERR, you get one of those per process, and when you do pipe-open, perl dup's each of STDIN/STDOUT/STDERR ...

so something something fork emulation keeps the filehandles alive and in use and undeletable

if you add close STDIN; close STDOUT; in sub thread, you'll get different output, like

Filehandle STDIN reopened as only for output

and Still cant remove file1 because No such file or directory instead of Permission denied
This isnt printed No such file or directory
