Very slow log

I have a revision in my repository where around 50,000 files were
modified (it was a global property change to clean up a pervasive import
issue, if you're wondering).

This makes svn log take for-freakin'-ever on any file that was involved
in this change if the log message passes through this revision. Is
there any way at all to make this go faster? Or to ... I don't know,
remove the revision from the output of log? It's all but a no-op, I
only made the change for cosmetic purposes -- the property name had a
typo, but wasn't mission-critical -- so this is especially galling.
