Comment:
I'm reassigning this to gigem, this is looking like a scheduler problem
now.
It looks like the scheduler is consuming alot of CPU, but the scheduler is
running at a lower threading priority so I don't think its CPU use is
actually causing the problem.
I think the reason it blocks the ThreadedFileWriter is probably because it
uses the mysql server which both uses the filesystem and is running at the
same priority as the the file writer.
