Are you using the win32/process version of fork? If so, what you are 
seeing is one of the differences between that and native fork on unix/linux.

For example, this code:

   puts "foop"

   Process.fork do
     puts "fork"
   end

on linux produces the following output:

foop
fork

and on windows (requiring 'win32/process' first) produces:

foop
foop
fork
