[NTG-context] stream sync (or \pushoutputstream)

[NTG-context] stream sync (or \pushoutputstream)

[Pablo Rodriguez]

Dear list,

I have the following sample:

    \showgrid
    \setuplayout[grid=yes]
    \starttext

    \startoutputstream[one]
       \startcolor[red]
         \dorecurse{4}{\input knuth\par\pushoutputstream}
       \stopcolor
    \stopoutputstream

    \startoutputstream[two]
       \startcolor[green]
         \dorecurse{4}{\input zapf\par\pushoutputstream}
       \stopcolor
    \stopoutputstream

    \null\page
    \synchronizestreams[one,two]
    \flushoutputstream[one]
    \page\flushoutputstream[two]

    \stoptext

With MkIV, stream one is always a line before stream two (11-12, 21-22,
31-32).

With LMTX, the output is less reliable, since stream one is one, two and
three lines before stream two (11-12, 21-23, 31-34).

In some cases, having synced streams is highly desirable.

Besides the output difference in LMTX, is there a way to get fully
synced streams?

Many thanks for your help,

Pablo
