Interesting. So are you saying that if an interrupt occurs, ensure
blocks are not *supposed* to be executed when rb_sys_fail() is called?
Dave's example did execute the ensure block when an interrupt was seen
but maybe there was no rb_sys_fail() involved?

What would be the remedy?  replace rb_sys_fail() with something else
in sysvipc.c?  I tried replacing it with rb_raise() but the same
result occurred.
