DisplayLink Forum - OSX drivers reading DisplayLink/.dl.xml many times a second?

I discovered opensnoop tool today and was using it to debug another problem, but the first thing I saw when running it was that DisplayLink appears to be reading /Library/Application Support/DisplayLink/.dl.xml several times a second.

Here's what a few seconds of running

Code:

sudo opensnoop

looks like to me. I'm using the latest DisplayLink OSX 2.4.beta1 and OSX 10.10.3 on a MacBook Air (11-inch, Mid 2011). I do not have a DisplayLink device (or any external devices) connected at present.

Code:

~ $ sudo opensnoop

Reporting because as a developer this "smells" like a place where code is not behaving as expected and might lead to bugs or suboptimal performance - would be interested if others can see the same behaviour on OSX?
