Hi,
	I need to generate a rolling 90%ile distribution figure for a (large)
	series of numbers as they arrive at the program. i.e after every say
	100 numbers it spits out the 90% so far.
	The value can be interpolated, but the code must be fast and have a
	minimal overhead i.e I am happy to accept small errors for speed.

	Code in any langauge (pref C) or an algorithm will be great...., or
	even some hints (but go easy on me I am a computer scientist - not a
	statistician!).

	Cheers
	Karl Funk.
