I found a bug, which seems to appear in Ruby 1.8.5 and 1.8.6  
under Windows, when net/ftp and the mysql 2.7.3 gem are used  
in the same program.

The but can be demonstrated with the following program:

require ‘mysql’  
require ‘net/ftp’

# (replace your host/user/pwd here)

Net::FTP.new(‘host’,‘user’,‘passwd’)

If I run this program, I get the error message

Error in my\_thread\_global\_end(): 1 threads didn’t exit

The error disappears if I either

- comment out the require ‘mysql’ line
- comment out the Net::FTP.new(…) line
