After putting the definition you proposed last in front of my minimal
example in mkiv beta 2015.02.03 it worked once and then not any more. I
also tried to remove all auxiliary files after a new pass.
But today I installed beta 2015.03.10 (complete fresh install as I keep
the older version in a renamed folder) and now the MWE with your extra
code renders repeatedly correct.
So this seems to be a workaround until you rewrite “write” as you said.
I will experiment further with tikz’ ‘remember’ picture mode.

this should help:
\unexpanded\def\writeviatex#1#2%
{\ifx\normalwrite\relax\else
% the \detokenize makes sure we don't expand \noexpanded macros
\normalwrite#1{\detokenize{#2}}%
\fi}
(in future version i might replace write completely)
Only partially because the saved positions from \pdfsavepos are
wrong.
in what sense wrong?
Content of the external file from MkIV (the entries on the first
page show 0
and the values on page 2 and 3 are always the same):
1:0:0
2:0:0
3:4661756:45255023
4:4661756:45255023
5:4661756:45255023
6:4661756:45255023
Content of the external file from MkII (different values for the first
and second position on each page):
1:6526435:46204089
2:4661756:45256000
3:6526435:46204089
4:4661756:45256000
5:6526435:46204089
6:4661756:45256000
ypositions can differ a bit because we use different fonts and so
does the interlinespace
But the values for both positions should be different which isn’t the
case for MkIV
and the first page saves 0 for the x and y positions.
It's a side effect of expansion at the wrong time (where such primitives
can return wrong values but at least they return something) but
something like this works:
\def\syst_write#1#2%
{\ctxcommand{write(\number#1,\!!bs\normalunexpanded{#2}\!!es)}}
\unexpanded\def\writeviatex#1#2%
{\ifx\normalwrite\relax\else
\normalwrite#1{#2}%
\fi}
