#325 multiple nodes -- same download directory?

[Zooko O'Whielacronx]

I constructed two files which have the same data in the
first half. (They are named "Stronger Than".)

When you try to download both of them at once bad
things happen.

This is because inside block wrangler, it tries to
merge these two downloads so that it doesn't download
the same data twice -- once for the first half of the
first file and once for the first half of the second
file. But this merging has a bug.

Hm. Actually this failure is sporadic. Just downloading
the two files doesn't always trigger the bug.

In fact, it might not have anything to do with those files.
It might be that I have to nodes downloading into the same
download directory, and sometimes they are downloading the
same files. ??

Yes, after some experiments I think that is what it is. A
nice solution would be for each node to name its tempdir
with its nodeId.

Bumping to v0.6.3 group. It sucks, but it isn't worth
taking the time to fix it for v0.6.2.
