i'm wondering if anyone else has seen this issue, or is aware of a workaround:
basically, using a System.Threading.Timer (or a System.Timers.Timer, which
internally uses the former) inside a Cocoa bridged app (both Monobjc or
MonoMac) will cause the application to crash on shutdown, inside
This seems to be a regression in Mono 2.10 - the same thing works fine in Mono
2.6 and earlier.
