Bug #2655: win32OLE processes lose their connection?
http://redmine.ruby-lang.org/issues/show/2655

Author: Roger Pack
Status: Open, Priority: Normal
ruby -v: ruby 1.9.2dev (2010-01-25 trunk 26409) [i386-mingw32]

The following code works in 1.8.6, not in 1.9.x...

require 'win32ole'
wmi = WIN32OLE.connect("winmgmts://")
processes = wmi.ExecQuery("select * from win32_process")
proc = nil
t = []
processes.each {|process|
  t << Thread.new { sleep 0.1
   process.setPriority 32
  }
}

t.each{|t| t.join}


error is:
