Hello Martin!

I see Kqueue provider for BSD family have limit on opened file descriptors when for next watched directories will be used generic watcher, but it's not good. The API be able to recursive watching, so open descriptor only for root watch directory. JNotify uses it internally. I would like to plan implement that provider in next 2-3 month.

Have you investigated the usage FSEvents for Darwin or have any thinks about?

Hi Mihail,
efsw uses FSEvents for OS X, i don't know why you're not seeing it:

Default limit on opened files on OSX:

#sysctl -a | grep kern.maxfilesperproc
kern.maxfilesperproc: 10240

And that's why you should be using the FSEvents backend :P

Oops. My fault. I badly researched the code
