[ruby-core:35450] [Ruby 1.9 - Feature #3436] Spawn the timer thread lazily

From: Mark Somerville <mark@...>
Date: 2011-03-07 10:28:28 UTC
List: ruby-core #35450
Issue #3436 has been updated by Mark Somerville.


Koichi has proposed a potential solution to this problem in a ruby-core thread[1].

It would be *great* to get some more testing and feedback on this, since it seems to be a problem for a number of users.

Feature #3436: Spawn the timer thread lazily
http://redmine.ruby-lang.org/issues/3436

Author: Maximilian Gass
Status: Open
Priority: Normal
Assignee: 
Category: 
Target version: 


 As discussed in http://redmine.ruby-lang.org/issues/show/1820, Ruby 1.9.1
 always spawns a timer thread which is required to handle scheduling of Ruby
 threads. Rubinius did the same and I suggested to only spawn the thread if it
 is required, only when Ruby threading is used. I don't know anything about the
 internals of Ruby, but could this method be used in MRI as well?
 
 The timer thread prevents the CPU from going idle and saving power/battery, so it would be nice to avoid it.
