I can reproduce the extra delay on MacOS X using a quick program that does 300
getservbyport() calls for ports 0-299.  /usr/bin/time -p runs of the program on
each platform (times are in seconds):

MacOS X 10.4.8 PPC 1.2GHz G4:
  real  14.67
  user   0.00
  sys    0.01

FreeBSD 6.1-REL Intel P4 2.8GHz:
  real   0.36
  user   0.31
  sys    0.02

Linux kernel v2.6.3-11 AMD Opteron 2.2GHz:
  real   0.18
  user   0.05
  sys    0.00

Now the question is, where in the documentation should we mention this?  User
guide?
