On non-windows systems, Solr includes an "oom killer" script.  This will 
find the Solr PID and execute "kill -9" on it if OutOfMemoryError is 
thrown.  We have an issue to add this capability for Windows as well, 
but the work hasn't been done yet.

If somebody has a Solr install that automatically restarts itself, that 
install has been altered and isn't what the project shipped.
