Ruby exceptions could defer constructing backtrace information if they held a
chain of frames representing the stack at that moment

Key: JRUBY-967
URL: http://jira.codehaus.org/browse/JRUBY-967
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.0.0RC2
Reporter: Charles Oliver Nutter
Assignee: Thomas E Enebo
It could be a reasonable optimization to defer generating the backtrace for a
given ruby exception by just holding a reference to a linked list of frames
that represents the call stack at that point. Unfortunately, there's currently
no way to chain frames together into a "spaghetti stack" of frames without some
new structure, since frame objects are re-entrant (when yielding to a block,
for example). Examine a way to make a linked list of lightweight frame
information that could be used to defer backtrace generation.
