[jboss-dev] Different Boottimes from pruning

[Bill Burke]

Ok, i did a profile of nothing in deploy/ and removed the weld and 
jbossweb deployers:

30% of total boottime was spent in addDeployer() which makes sense since 
WebServices adds like what?  30 deployers?  That 30% of time is solely 
in sorting the deployers.
