[jcifs] Multiple host SMB Crawler

[Dan Dumont]

Those exceptions at the beginning should be happenening all at once...   3
are started at the same time, they should throw at the same time.

They don't.

With a mixture of real and bogus IP's this is what I get. Looks right to me.
If I
add routeable but non-responding hosts it takes much longer because of the
Connection timeout exceptions but it finishes eventually and still does what
I
expect. What do you expect to happen?
