"tests running forever" issue within fiber test
-----------------------------------------------
Key: JRUBY-1303
URL: http://jira.codehaus.org/browse/JRUBY-1303
Project: JRuby
Issue Type: Bug
Reporter: Charles Oliver Nutter
Assignee: Thomas E Enebo
Only saw this once, but I wanted to record it here in case it comes up again
and we need to investigate it. This was during the compiler portion of the unit
tests (not the specs).
