(require 'spyscope.core) significantly slows lein startup time

[philc]

I followed the instructions on the readme a few months ago and only recently noticed that requiring scope adds a full 1s to every lein task I invoke. That is really surprising for such a small library. We should either fix this or document it.

Without :injections [(require 'spyscope.core)] in my profiles.clj:

lein new app lein-test && cd lein-test && time lein run
lein run  6.21s user 0.32s system 219% cpu 2.969 total

With:

lein new app lein-test && cd lein-test && time lein run
lein run  8.41s user 0.38s system 226% cpu 3.886 total

This is on a recent Macbook Pro.

lein -v
Leiningen 2.3.4 on Java 1.6.0_65 Java HotSpot(TM) 64-Bit Server VM

Hey Phil--I think that this could only be caused by the clj-time dependency. I'm inclined to not remove the features that use clj-time. You should only see the increase for profiles that include spyscope, which should only be development/repl profiles.
