'From Squeak3.10beta of 22 July 2007 [latest update: #7143] on 4 November 2007 at 7:54:52 am'! "Reporter: andreas Summary: 0006576: Delay is not thread-safe Description: Delay is not thread-safe since currently the calling process updates the internal Delay structure itself. If the process gets terminated while doing this (e.g., adding/removing from SuspendedDelays) the whole system is left in an inconsistent state and breaks. Attached changes fix the problem. Additional Information: It is *very* hard to recreate this problem under controlled circumstances which is the reason why there are no tests accompanying the changes. I've not been able to create the problem on a single machine but we have seen it for months on our servers and with these changes the problem simply went away. "!
