Looks like the current CVS changes to the connections code have some unusual results, but still lots of firewalled UP's (usually 2/3).

more connections at first--75 after 30 minutes; 83 after 80 minutes; 63 after 102 minutes, and 62 after 9 hours. I'm used to seeing 60 (30 UP + 30 leaves).

-acting as a leaf AND an Ultrapeer for more than 30 minutes? (enabling the incoming searches checkbox pops up the shielded leaf message, yet searches are rolling by faster than I can read, like an Ultrapeer). Details below.

-when 75 hosts, 36/37 UP's were incoming, and 21 firewalled.
-when 63 hosts, (33 UP's ; all incoming), still 21 firewalled
-when 62 (32 UP's ; all incoming) 20 firewalled
