Although a little late I try to answer that one.

IMHO this is the setting that minimally affects stability of a program.
Imagine a server that spawns threads for requests. If any of those
threads dies due to some error you don't want the whole server to stop.
The proper way to do it is IMHO to handle errors from within the thread:
Thread.new do
begin
raise "aa"
rescue => e
$stderr.puts "ERROR: #{e}"
else
$stdout.puts "fine"
end
end

That's another story and possibly a good suggestion: have ruby print a
message to STDERR if a thread terminates with an uncaught exception.
