Craftbukkit 798/803 - High cpu

It still works, just uses 100% CPU with lag as others are having, some times even 2 cores; perhaps from java trying to do garbage cleaning?
I didn't bother trying to do "interact with desktop" but that would probably fix it also, but I don't really wanna do that lols.
I think you can also imitate it with javaw.exe instead of java.exe as it's a windowless way to run jars.

 

Using the jline argument during launch, build 860:
It seems that craftbukkit spends about 5 mins spewing error messages into the console, before going quiet. It then simply dies about 5 mins later. The last log looks like this:

This happens consistently. Even the time scale is replicable.

I realise that this problem seems unique to instances of craftbukkit which have been daemonized, but I do all of my server operations over SSH (as I would have thought most people would) and if the server is linked to the terminal then it dies when I disconnect.
