 Log Message:
 PR bin/36532 (perhaps)
 
 This is more or less the same patch as provided in the PR
 (just 11 years later, so changed a bit) by woods@...
 
 Since there is no known way to actually cause the reported crash,
 we may never know if this change actually fixes anything.   But
 even if it doesn't it certainly cannot hurt.
 
 There is a potential race which could possibly explain the issue
 (see commentary in the PR) which is not easy to avoid - if that is
 the actual cause, this should provide a defence, if not really a fix.
