CLONE -JRuby IOHandlers are not thread safe
-------------------------------------------
Key: JRUBY-1227
URL: http://jira.codehaus.org/browse/JRUBY-1227
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.0.0
Reporter: Nicolas Modrzyk
Priority: Critical
Fix For: JRuby 1.1.0
The buffer for IOhandlers are not thread safe, meaning some very nasty things
happen. A test case:
oo = open("file1", "w")
t = Thread.new { 10_000_000.times { oo.puts "foo bar"} }
10_000_000.times { oo.puts "baz mid"}
t.join
This will fail almost certainly; especially on dual core machines.
