Both \dorecurse and \doloop leave the value of \recurselevel to its
previous value. \dofastrecurse does not and sets it to the last value.
\starttext
\recurselevel
\dorecurse{6}{Hello }
\recurselevel
\doloop{\ifnum\recurselevel>6\relax \exitloop\else again \fi}
\recurselevel
\dofastrecurse{1}{6}{1}{and again}
\recurselevel
\stoptext
I do not think that any change is needed (One shouldn't use \recurselevel
outside a recursion macro anyways). I was just surprised to find that
recurselevel was defaulting to such a weird value in xetex.
