hi all,

apologize if this is not the right list -- in the latest svn of numpy 
unique seems to be taking a long time with "nan"

reproducible error:

import numpy as N
import numpy.random as R

x = R.standard_normal((100000,))
x = N.around(x * 100.) / 100.

print len(N.unique(x))

x[0] = N.nan
print len(N.unique(x))

x[0:50000] = N.nan
print 'OK'

print len(N.unique(x))

Leukemia and Lymphoma Society!
