On windows, failing to import `os.fork`

[xylar]

In our CI on conda-forge, when we try to use the latest release under Windows, we see:

import: 'radical.gtod'
Traceback (most recent call last):
  File "D:\bld\radical.gtod_1715454527932\test_tmp\run_test.py", line 2, in <module>

    _orig_os_fork    = os.fork
                       ^^^^^^^
AttributeError: module 'os' has no attribute 'fork'

It seems like this needs some sort of if around it to handle the Windows situation where os.fork doesn't exist.

It could also be that this is caused by me messing something up on conda-forge (e.g. by building the conda package as noarch: python). If so, I'll close this.

Ah, sorry, I see that Windows was just skipped previously on conda-forge. My mistake!
