File monitor

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 elivate spamming changes)

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