Comment(by int-e):

 Replying to [comment:12 igloo]:
 > Thanks for working on this. I haven't been following this issue, but is
 there a patch that you think should be applied now? And is there a test
 that it fixes?

 I've implemented a testcase now, based on the sample program above; the
 patch that should definitely be applied is the minimal [attachment:0001
 -Fix-System.Timeout.timeout-leaking-Timeout-exception.patch] one.

 The second patch is about improving performance and needs a second pair of
 eyes.
