Crashes if too many publishes occur

[adamvr]

node-growl spawns a new growlnotify process for each notification and if we get a whole heap of publishes it tends to hit the process limit.

child_process.js:477
    throw errnoException(errno, 'spawn');
    ^
Error: spawn EMFILE

    at ChildProcess.spawn (child_process.js:477:11)
    at child_process.js:375:9
    at Object.execFile (child_process.js:285:15)
    at child_process.js:252:18
    at growl (/usr/local/lib/node_modules/mqtt-growl/node_modules/growl/lib/growl.js:187:3)
    at Connection.<anonymous> (/usr/local/lib/node_modules/mqtt-growl/mqtt-growl:64:9)

    at Socket.emit (events.js:67:17)

Consider migrating to something that has a persistent connection to the growl server or throttle node-growl somehow.

Stopgap solution implemented with -d parameter. Still not really good enough.
