Backport #3336

Updated by jeremyevans0 (Jeremy Evans) over 5 years ago

=begin 
  
  The IO.select() method leaks memory on the Windows platform (tested mingw32). This prevents any long-running service process from working properly on Windows and is a blocker for application development. Using LeakDiag, I tracked this down to an fdset not being freed properly, but I am not sure what the proper solution is yet, 
 
  To quickly reproduce this issue, run the following snippet: 
 
  require 'socket' 
  a = TCPServer.new(8888) 
  while true 
    IO.select([a], nil, nil, 0.01) 
  end 
 
  Watch the memory usage spike up in the task manager or process explorer.
