I came up with a simple Ruby snippet that reproduces the problem. I'd
appreciate it if other Cygwin users would try it. You can change the
"cause_failure = true" line to say false and it will run.

--urandom_test.rb------
# Test failure of reading /dev/urandom after failed require

# this method is from the Rails' source secret_key_generator.rb
def generate_secret_with_urandom
  return File.read("/dev/urandom", 64).unpack("H*")[0]
end

cause_failure = true

begin
  require 'nonexistent_file'
rescue LoadError
  puts '' unless cause_failure
end

puts generate_secret_with_urandom
-----------------------

So far, the strace output of this is too low level for me to follow.
Perhaps it will be clear to a regular Cygwin hacker.

BTW, I'm running "ruby 1.8.6 (2007-03-13 patchlevel 0) [i386-cygwin]".
