I think if you see waiting for work constantly with neoscrypt you are using too many threads for your GPU. Try using a lower -g setting. You could also try different worker difficulty setting, or adjusting scan/queue/expiry on your miner. I use: -scan-time 1 --expiry 1 --queue 0

It may also just be a bug with the ancient version of cgminer they're using...

HashX will move out of beta when I finish building purchase processing of HashX orders into the site, so you're safe for a bit longer It's in progress though!
