- there are a number of places that assume that the number of maximum
open files is fixed
- the file descriptor limit needs to dynamically adjust

I have code for this locally, which I need to clean up and push.

Note that watching large numbers of files is a big issue only on macOS:
on other platforms file-watching actually watches directories, so itʼs
much harder to run into the limitations (this includes MS-Windows)

Once itʼs finished we can discuss whether it should be turned on by
default: based on past experience, I think it would be default-off in
29.1 (although maybe default-on for macOS if weʼre feeling
adventurous)
