Note, that ServletContext.getContext(String) allows interaction
between different web applications on the same server.  That is when
crossContext=true for the application.

I wonder, how much will be the overhead from having several JVMs, each
with its heap.

I think that /work folder sharing is out of question. Most of concern
here is with Jasper, but there can be also other files, and files
written by applications.

The /webapps folder sharing depends on whether autodeploy feature is
enabled. Expanding deployed wars and deleting folders when undeploying
must be done in a single thread. Otherwise there can be security
issues.
