[rt-devel] Listing.html, # of tickets\

[Jesse Vincent]

If the ->Count is done _after_ the ->_DoSearch method is called by internal 
code, however (say by pulling out the first row), it will report
exactly how many rows are in the current result set.  The reason
for the disparity is that doing a whole bunch of selects just to get counts
turns the rest of the system into molasses :/  
I'm currently investigating some changes in the architecture for 2.2 that will
significantly improve the performance of all this stuff and get ->Count to be
more accurate as a happy side-benefit.
