Ok, I think I could remove some of the JAR from the CL, but far from
everything. So not sure about the net gain here

It's sort of custom built, so I had to buy it myself. It's pretty cheap though.

Removing the binding manager is possible, and gave the following performance:
jbossweb-standalone: 4.5s / 80.5MB
jbossweb-standalone (no binding manager): 4.0s / 79.1MB

So the startup time gain is there, but memory usage is too high.
Overall, I don't think dropping the binding manager is a very good
idea.
