Is it possible to have each section on a new page except for sections of the bibliography?

Question

This is a continuation of my previous question. I have the following line of code in my preamble

\pretocmd{\section}{\ifnum\value{section}=0 \else\clearpage\fi}{}{}

which puts each section on a new page except for the very first section of a chapter. My problem is that if I use something like

\printbibheading
\printbibliography[
 heading=bibintoc,
 keyword={books on things},
 title={Books on Things}
 ]       
\printbibliography[
 heading=bibintoc,
 notkeyword={books on things},
 title={Everything Else}
 ]

in the document body, then the bibliography title and the bibliography sections are also placed on 3 different pages, whereas I want them to stay together. My question is thus

Is there a way to modify the aforementioned code of line in such a way that it does not apply to the bibliography (or some such workaround)?

Thanks!

You can use the following in your preamble:

\newif\ifinbib
\pretocmd{\section}{\ifinbib\else\ifnum\value{section}=0 \else\clearpage\fi\fi}{}{}
\pretocmd{\printbibheading}{\inbibtrue}{}{}

It provides a new conditional \ifinbib (false by default) which is set to true as soon as you \printbibheading. After this, the conditional for \clearpage is never called.
