Issue #9115 has been reported by cphoenix (Chris Phoenix).

----------------------------------------
Bug #9115: Logger traps all exceptions; breaks Timeout
https://bugs.ruby-lang.org/issues/9115

Author: cphoenix (Chris Phoenix)
Status: Open
Priority: Normal

Category: 
Target version: 
ruby -v: ruby 2.0.0p247 (2013-06-27) [i386-mingw32]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


Line 577-579 of logger.rb

      rescue Exception => ignored
        warn("log writing failed. #{ignored}")
      end

Thus, when the system times out in the middle of writing a log message, it warns "log writing failed. execution expired" and just keeps right on running.

This is true in 1.9.3 as well. I haven't looked at older versions.

Pardon me while I go grep "rescue Exception" in the entire Ruby codebase, and see whether I can reliably use Timeout at all...

OK, you might check out C:\Ruby200\lib\ruby\gems\2.0.0\gems\activerecord-3.2.13\lib\active_record\railties\databases.rake

All the other "rescue Exception" seem to re-raise it, except maybe C:\Ruby200\lib\ruby\2.0.0\xmlrpc\server.rb and C:\Ruby200\lib\ruby\gems\2.0.0\gems\activesupport-3.2.13\lib\active_support\callbacks.rb
