Please see attached for two test cases, courtesy of Yutaka tanida, that
reproduce this problem without PostgreSQL involved. Actually,
mmaptest2.c further isolates the problem down to mmap()/fork() by
removing cygipc from the equation.

Hmm ... it seems to be terrible.
I create a program to re-produce this probrem . I think it's a bug of
fork().
