For now, this sounds fine to me. There are some (vague) plans to support
sub-second resolution some time in the future - in that case using a
minimum timeout of 2s might not be an optimal choice. However, currently
this should not be a problem in real life and it should be easy to adopt
in the future, so I'll use that patch for now.

I'll test it before uploading the package. Thanks again for providing
the patch!
