Last time I actually tried to measure how "wasteful" that was (repeated calls 
to a function doing a sqrt(), virtual or not), I had to raise the number of 
iterations to 1 million before there was any measurable difference (about 1 
second out of 20 or so). That was on a P-III 600 MHz.

'virtual' overhead will be drowned in statistic noise as soon as your function 
is doing anything serious, like IO.
