Frequent EBUSY error on changed file

[madbarron]

When I have the karma server running and I save a tracked file, it often crashes karma with:

ERROR [karma]: { [Error: EBUSY, open 'c:\myfile.js']
  errno: 10,
  code: 'EBUSY',
  path: 'c:\\myfile.js' }
Error: EBUSY, open 'c:\myfile.js'

I have set autoWatchBatchDelay: 1000 in my karma.conf.js, but this error occurs before the delay takes place.

I am in Windows 7, using Sublime Text 3, karma 0.12.24, node 0.10.32

I have the same issue. Maybe it was the last Sublime update?

Currently, files are loaded as soon as a modification is detected. If a file handle is not released yet, karma crashes (or tests are aborted with 095cfb4).

I believe the best fix would be to load modified files after the autoWatchBatchDelay It would also have the nice benefit to reload a file once if it is saved multiple times quickly.

Yeah, I expected that karma wouldn't attempt to touch the files until autoWatchBatchDelay. Your PR looks like a reasonable workaround.
