The main change from 3.32 (which worked) to 3.4x (many problems) was
multithreading.  Earlier version placed the original html files into the cache
and eventually the modified ones on disk.  With multithreading, you can't
concurrently write to the cache so things went to *.tmp and delayed folders.

Since 3.4x has so many unresolved problems, I recommend 3.32
