Yes, I tracked it down to the mechanism to create numbers with
compounding.  It was trying lots of numbers before giving up.  And
repeating that at every position.

Unfortunately all existing Vim binaries don't know the 
NOCOMPOUNDSUGS flag, thus the only way to make the spell file work well
is by removing the compounding rules.  So we don't have correct checking
for "th" and "nd" after a number.  Oh well.
