Alas, this only postponed the agony of the assert;  I could write
a few files after the patch, but I still eventually got a crash.
I think that the problem may actually *be* the assert.

I checked, and ext2fs seemed to have been working just fine before 
the commit that put in the assert;  when I added the assert to
that working code, the assert triggered.  Removing the assert from
the code doesn't seem to exposed any more bugs.

I don't really feel comfortable enough with the filesystem code
to say all this with any confidence.  Could someone else take a look
and tell me if I'm crazy?
