Please do not try to use the undo/revert Perl scripts if you do not know 
exactly what you are doing.

I don't want to sound too harsh but let me quote from the README file 
which you must have read or you wouldn't have been able to run the scripts:

"Be sure that you feel confident to fix anything you might break. If you 
do not know your PUTs from your GETs, if you do not know the details of 
API 0.6, or know what changesets are and how they work, then DO NOT USE 
THIS SOFTWARE."

First of all, changesets will never disappear from the history page. All 
you do when "reverting" is you add a new version that re-creates the 
state something was in before a change.

Second, the revert code is not really optimized for large-scale 
deletions like the one you're attempting. If I am not mistaken it will 
try and download the history of every one of the 20k nodes in your 
changeset when instead it should simply try and delete them...

Why it didn't work I don't know, it is entirely possible that some error 
conditions do not lead to proper error messages.

I'll try and fix it.

Bye
Frederik
