Issue #5891 has been updated by Eric Hodel.


I concur, it appears that ruby-doc.org is not processing prelude.rb per the .document in ruby.  From ruby-trunk:


  $ ri20 --no-standard -d .ext/rdoc/ Mutex.synchronize | sed -e 's/^/  /g'
  Mutex.synchronize
  
  (from /Users/drbrain/Work/svn/ruby/trunk/.ext/rdoc)
  ------------------------------------------------------------------------------
    mutex.synchronize { ... }
  
  ------------------------------------------------------------------------------
  
  Obtains a lock, runs the block, and releases the lock when the block
  completes.  See the example under Mutex.

Bug #5891: prelude.rb rdocs are not included on ruby-doc.org

The documentation for Mutex#synchronize and Thread.exclusive, the two methods defined by prelude.rb, is missing from ruby-doc.org.
