Should this work, or should we rather use "~" and "\," as in the past?
repaired in next beta (was unwanted side effect of optimization)
"~", by the way, appears not to be respected in math mode; example:

\starttext
$3\times 10^{-9}~\text{m}$

$3\times 10^{-9}\,\text{m}$
\stoptext
no surprise, as math has its own spacing model so it all depends on the
definitions; i'm not even sure if we shoule support an active ~ in math
mode at all

I do not have any strong feelings about this, but do believe that "~" has always provided an unbreakable white space in TeX, both in text and math mode. I also feel that "~" is more readable than "\,".

The activeness of ~ isn't that important, but there really should be
a non-breakable space in math mode, and an active ~ is the most logical
choice because of 20 years of TeX input. You can pick something else,
but it is definately needed, and it should be shorter than
  "\penalty10000 \ "

Best wishes,
Taco
