watch mode chokes due to file limit (Linux)

[FND]

On Linux, if node_modules gets a little bigger (which, of course, can happen quite easily), fractal start --watch throws an ENOSPC exception within chokidar:

Error: watch …/components ENOSPC
    at exports._errnoException (util.js:1020:11)
    at FSWatcher.start (fs.js:1443:19)
    at Object.fs.watch (fs.js:1470:11)
    at createFsWatchInstance (…/node_modules/chokidar/lib/nodefs-handler.js:37:15)

Turns out this is because Linux's inotify imposes a fairly strict limit on the number of files being monitored (see for example remy/nodemon#214 (comment)).

FWIW, when we ran into this with faucet-pipeline, we resorted to catching this error and offering an option to limit watching to certain directories:
https://github.com/faucet-pipeline/nite-owl/blob/906f1173e5cf71ff5f4794add4ad60a21fd438e3/index.js#L29

Perhaps Fractal could automatically exclude node_modules when invoking chokidar?
