Ugh -- please fix indentation. This is not proper Linux code.
If you have the -vast majority- of code on an indented branch, as you
have here, then you should either add an early 'return x;' or a goto,
and unindent the main body of code.
I'll let our new tulip maintainer see what he thinks about the
implementation. Seems fairly sane to me, but should at least get an "it
works" test.
