 This little script causes segmentation faults on my machine (unibody
 MacBook with Core 2 Duo)
 (using the 0.6 release version)
 {{{
 #!/usr/bin/env macruby
 framework 'calendarstore'
 50.times do
   Thread.new do
     loop do
       pred = CalCalendarStore.eventPredicateWithStartDate(NSDate.date,
 endDate:NSDate.date,
 calendars:CalCalendarStore.defaultCalendarStore.calendars)
       CalCalendarStore.defaultCalendarStore.eventsWithPredicate(pred)
       sleep 1
     end
   end
 end
 sleep 1
 }}}

 Most common is this error:
 {{{
 $ ./test.rb
 unknown: [BUG] Segmentation fault
 MacRuby version 0.6 (ruby 1.9.0) [universal-darwin10.0, x86_64]

 Abort trap
 }}}
 but I get this as well:
 {{{
 $ ./test.rb
 SEGV recieved in SEGV handler
 unknown: SEGV recieved in SEGV handler
 }}}

 Since the programm exits on the seg fault, I didn't manage to get a
 backtrace with macrubyd.
