Editing File monitor (section)

=Simplified File Watching Interface=

==Use cases==
* Watch for source code changes and rerun unit tests
** Shell command, should be cancelable
** Needs to be filterable (ie .go, .cpp, .hpp)
* Watch for kernel/nvidia driver changes and copy to EFI

==Requirements==
* Must support cancelable shell command.
* Functions/GoRoutines can't be canceled.
* Different editors have differnt save strategies.
* Most changes result in multiple events (touch for example CREAT+CHMOD).
* Should support a delay (could stop spamming changes).
* Delay should be reset each time a new action occurs.

Modification time? Might not help if you copy an old file onto a new one...

==Example==
 file: /usr/lib/modules/linux.so
 cancelable: yes
 delay: 10ms
 action: cp /usr/lib/modules/linux.so /boot/efi/blah.so

 file: /src/program
 cancelable: yes
 delay: 10ms
 action: go test ./...

 file: /mnt/storage/large_files
 cancelable: no
 delay: 10ms
 action: go func {SomeLongRunningAction()}
