Each webapp is based on spring and hibernate doing a lot of I/O during initialization.

initializes its wepapps sequentially. So despite the fact, that our tomcat-intance runs on

Nope.

Not that I can think of off the top of my head. Just that no-one has
felt the need to scratch that particular itch.
Both start and stop needs to be taken care of.
If you want to propose a patch, this might provide a starting point:
https://issues.apache.org/bugzilla/show_bug.cgi?id=46264
I've added some review comments to that patch that you may want to
consider when writing a patch.
If you need any help with the patch, just ask here.
Thinking about this has got me interested. If you decide not to take a
look at writing a patch for this, I'll probably take a look - maybe
later this week.
