Can you try running the test suite again? This might be some kind of race 
condition. I've run the tests on NetBSD 5.1 amd64 and everything passes.

That's definitely a bug of the test itself... if the box is slow enough it is 
easy to notice.

There is to test this better but 99% probability that's it.

I can only test this again tomorrow night.
The host is very slow, specially IO.
Is there a way to run specifically just this test ?

Miguel if the host is really slow we know what the problem is.

Usually the old BGSAVE should be already ended, so there is no error in almost 
every kind of system, but the slowest. There is to fix this issue but it is 
definitely not a real bug.

Cheers,
Salvatore
