No.  The kernel needs to be modified to move the shared page out of the way so
that the program can mmap() the top page of user memory.

With an unmodified kernel, it should be possible to trigger the problem by
writing a program that installs a signal handler for some signal and then
sending itself signals by calling kill() in a loop.
