How to avoid that \writetolist becomes a page-breaker

How to avoid that \writetolist becomes a page-breaker

[Marco Pessotto]

Probably due to my abuse of \writetolist, I noticed that inserting
\writetolist right after \subject makes TeX to think that it can break
the page there without problems.

See the following minimal example:

%===============cut here=============

\definelist[myrandompart]

\starttext

\dorecurse{12}{
\input reich 
}
\subject{\bf Wrong!}
\writetolist[myrandompart]{It's a test}

\input knuth

\page

\dorecurse{12}{
\input reich 
}
\subject{\bf Correct!}
%\writetolist[myrandompart]{It's a test}

\input knuth

%===============cut here=============

I'm pretty sure the solution is out there.
Some hints would be very welcome.

Thanks in advance

To answer to my own question, it looks like that

\subject{\bf My title!}
\dontleavehmode
\writetolist[myrandompart]{}{It's a test}

works. The question if is this the right thing to do, still remains,
though

it's quite ok as long as you realize that it introduces 'something' in 
the text stream, so

xxx

\dontleavehmode\writetolist[myrandompart]{}{It's a test}

xxx

is actually:


xxx

[something written to a list]

xxx

so when whitespace is setup, in some cases you can get some extra

also, the [something ...] can end up on the current page or the next 
one, depending on the circumstances

in practice it's no real problem as one will do explicit writes inside 
boxes or so

i.e. just bind the write to some text
