the \def\my... needs to go before the \placebookmarks, otherwise it is 
indeed unknown; tex works top-bottom

also, it may make sense to use \abbreviation[mycs]{...} since those 
commands are normally taken care of in decent ways

[alternatively you can do things like

   \appendtoks\def\mycs{WHOW}\to\everysanitize

to get your own clean up in bookmarks]

This solution doesn't seem to work (either because \everysanitize
is not issued by the PDF bookmark sanitizer or because it does not
become effective soon enough). I found that a possible alternative
is

\immediate\writeutility{%
    c \string\def\string\mycs{whatever we want}%
}

hm, before i look into it someone should make me a minimal test file (never 
use bookmarks myself)

that is a real terrible hack, isn't it?

\setupinteraction[state=start]

\placebookmarks[chapter]

\def\thisisatest{This is a test}

\starttext

\chapter{\thisisatest}

\stoptext

Yes. I propose some form of "generic (PDF) sanitizer"
which gets called before the placebookmarks but can be configured
anywhere in the TeX source (and thus needs to be saved to the
auxiliary file). Something like:

\startPDFsanity
    commandname        {expansion in PDF form}
    anothercommandname {another expansion}
    andsoon            {and so forth}
\stopPDFsanity

You could even define sanitizer as a class and then have PDF
sanitizers, PS sanitizers etc, all with a common interface like
the above.

The problem is perhaps that bookmark writing does occur at the start
of processing the .tex file and not at \starttext? The macro is
defined before \starttext.

As I recently encountered this problem too, I looked up an old
discussion in 1999. There you gave me this macro:

\long\def\sanitizePDFdocencoding#1\to#2%
  {\enablePDFcrlf
   \enablePDFdocencoding
  %\honorunexpanded % otherwise problems with "e etc in de 
   \edef#2{#1}}

The \honorunexpanded was new than. I have no idea why it is
commented out now?

(this is a 10 months old ConText or so, haven't got around to get the
new font stuff working).
