Perhaps I'm misunderstanding, but I thought it is not known yet whether the cause of the original problem is ASLR.  I
remembersomeone referred to anti-virus software and something else.  I guessed that the reason Noah suggested 1 - 5
secondsof retry is based on the expectation that the address space might be freed by the anti-virus software.
