Awesome, thanks ;).

I committed the iov_len fixes as you sent them.  They're fine for now.
I think they'll break OSX, as I kind of remember it having a weird
iov_len type.  But getting crfsd building in OSX is going to be a treat
for many more fundamental reasons ;).

I did the config file size fixes a little differently.  I had it check
that the file size wasn't crazy and then just stored it in an unsigned
int while we worked on it.  That seemed easier.

Oops.  Thanks, I fixed that.  I also committed your fixes to the file
itself.
