[R] confint.multinom() slow?

Dear R-helpers,

I'm doing a bivariate analysis with two factors, both with relatively many levels:

  1. clustering, a factor with 35 levels
  2. country, a factor with 24 levels

n = 12,855

my.fit <- multinom(clustering ~ country, maxit=300) converges after 280 iterations.

I would like to get CI:s for the odds ratios, and have tried confint()

my.cis <- confint(my.fit)

I started confint() a few hours ago, but now I'm getting suspicious, since it hasn't terminated yet. Perhaps I just lack the reasonable patience, but is such a long computational time for confint() to be expected here?
