Subject: File#flock with LOCK_SH causes Errno::EBADF on Solaris

Hi all,

Ruby 1.8.6
Solaris 10

# flock_test.rb
fh = File.open('flock_test.txt', 'w')
fh.puts 'hello'
fh.flock(File::LOCK_SH)
fh.flock(File::LOCK_UN)
fh.close

On Linux no error is raised. On Solaris 10 I get:

flock_test.rb:3:in `flock': Bad file number - flock_test.txt
(Errno::EBADF)
        from flock_test.rb:3

What's the deal?

Thanks,

Dan
