I currently have a problem setting the indices of a book. A minimal example

\defineregister[mouse][mice]
\setupregister[mouse][n=2,balance=no]

\defineregister[house][houses]
\setupregister[house][n=2,balance=no]

\starttext
rodents\mouse{rats+large}

home\house{ranch+split-level}

\page

\placeregister[mouse]

\placeregister[house]

\stoptext

places the second register on its own page. How can I get the second
register on the same page as the first?
