I have written a second test, where one thread constantly xors a
bitset with another, while the the second thread uses toString() and
looks if the bitset has one of the two possible forms.
JDK1.2 doesn't synchronize; xor() and toString() aren't atomic.
(Luckily, jdk1.2 uses native threads, where such race conditions can
be easily provoked)
