Be flexible about TCP RST and SOCK_DESTROY poll return values.
The intent of PollOnCloseTest is to ensure that SOCK_DESTROY
behaves in the same way with respect to poll() as receiving a TCP
RST packet would.
Unfortunately, due to a race inside the kernel, the return values
of poll() in these circumstances is non-deterministic. The race
when processing a TCP RST has been fixed, but the one when
processing SOCK_DESTROY has not.
Ensure that the test does not insist on specific return values on
kernels that do not guarantee them.
Also ensure that any assertion failures in SocketExceptionThread
are passed on to the main thread and properly cause the test to
fail.
