This is a workaround for a strange hang on fork() when Popen is called with
a preexec_fn (see #58). If the environment variable
IMAGEIO_FFMPEG_NO_PREVENT_SIGINT is not empty, preexec_fn is set to
None.

Thanks! Three comments.

  • It would be nice if "0" and "false" also resolve to Falsy. See e.g. this discussion. A quick version could be something like os.getenv(...).lower() not in ("", "0", "false").
  • Would you mind adding a section before the API section in the README that lists the environment variables? This one and IMAGEIO_FFMPEG_EXE. Otherwise I can do that after merging this PR.
  • Could you run black . on the code to fix formatting? :)

This is a workaround for a strange hang on fork() when `Popen` is called with
a `preexec_fn` (see imageio#58). If the environment variable
`IMAGEIO_FFMPEG_NO_PREVENT_SIGINT` is not empty, `preexec_fn` is set to
None.
