[armedbear-devel] fast-boot-preloading branch merged to trunk

After finding on the fast-boot-preloading branch that the experiment
worked out: delaying access to the reflection API in order to save
performance worked!

Comparing  the branch performance of loading ABCL on Google App Engine
to the trunk, the trunk took rougly 19 seconds to load (theoretical
performance) while the branch only took 11 seconds.

Seeing this benefit, I decided to merge the code back to trunk once
the branch was stable enough. Today was that moment: I found the last
reason the branch was failing the ANSI tests (I needed to increase the
runtime stack). Given this status, the merge of the branch to the
trunk just got committed.

The work isn't fully done though:
 1. The same approach can be implemented for macro-functions
 2. Functions loaded through EVAL-WHEN during file compilation can be
addressed the same way

Anybody with time to help out on either is heartily invited to join
the effort and see how much compile time and boot time can be saved.

With kind regards,
