There is a more portable way to extract the schema information, using

I am a clojure newbie. I am using clojure 1.5.1 and I am experiencing the
issue as described here:
https://groups.google.com/forum/#!msg/clojure-dev/4CtSVWcD15A/shpMuyjMpxsJ
I could not find this issue in jira. So not sure if its been addressed. I
can put it in jira if its still not there.
I have a task on my infinite todo list to analyze these load times. I know that
Tim B has done a bit of work on it in the past too. Rich has mentioned it to me
a couple times so I know it's something he's concerned about.

What Mikera probably wants to demonstrate, and I agree with him, is that
the slow startup time not being due to JVM proper, it's in the current

Our use case is quite a bit different. We treat our database schema as part
