Hi,
LuaTeX hangs in the following example, it is related to the optional argument
for \startTEST.
\def\startTEST
{\dosingleempty\dostartTEST}
\long\def\dostartTEST[#1]#2\stopTEST
{\bgroup
\processaction
[#1]
[bold=>\bf,
italic=>\it
unknown=>\tf]%
#2%
\egroup}
\def\TEST#1%
{\startTEST#1\stopTEST}
\def\defineTEST[#1]%
{\processbetween{#1}{\TEST}}
\defineTEST[MYTEST]
\starttext
\startMYTEST
text
\stopMYTEST
\startMYTEST[bold]
text
\stopMYTEST
\stoptext
Greetings,
Wolfgang

unrelated to luatex ... processbetween takes args one by one
\def\dostartTEST[#1]%
{\bgroup
\processaction
[#1]
[bold=>\bf,
italic=>\it,
unknown=>\tf]}
\def\dostopTEST
{\egroup}
\def\defineTEST[#1]%
{\setvalue{start#1}{\dosingleempty\dostartTEST}%
\setvalue{stop#1}{\dostopTEST}}
\defineTEST[MYTEST]

and why did it work with pdfTeX?

And can't use this method, I have to read the content between
\startTEST and \stopTEST in my module because the content
is processed twice to get information from the the first pass in
the second pass.

done, problem found.
the following command in toks-ini.tex cause the freeze in mkiv:
\def\dograbuntil#1#2%
{\long\def\next##1#1{#2##1}\next}
the correct definition should be
\def\dograbuntil#1#2%
{\long\def\next##1#1{#2{##1}}\next}
