Problem with itemization (again)

[Marcin Borkowski <mbork@atos.wmid.amu.edu.pl>]

Hi,

sorry to be a bit repetitive, but this still doesn't work as expected
(in MkII, but see also below):

\starttext                                                                      
\startitemize[intro]                                                            
\dorecurse{12}{%                                                                
  \item \dorecurse{\recurselevel}{This is some intro. }Intro ends here.         
  \startitemize[intro,columns,two]                                              
  \dorecurse{4}{%                                                               
    \item \dorecurse{1}{This is a test. }End of the test.                       
  }%
  \stopitemize
}%
\stopitemize
\stoptext

(see page 2 and 3).  I guess nothing wrt. itemizations changed in the
new beta (I tested the above example in the online ConTeXt), so it's no
surprise, but I still have no clue as to the reasons and any remedies.
I use two-column itemizations *a lot*, so this is a serious problem for
me...  Any ideas how to prevent the unnecessary page break?

PS.  I have just noticed that this works correctly with luatex!!!  And
so do unpacked two-column itemizations!!!  That's just great!!!  So my
question now becomes: does this mean that MkII is just obsolete for me
and I should upgrade to MkIV?

And two more things:

1. I have noticed that "unpacked" itemization in columns has the
whitespace between items equal to one line.  Is it possible to make it
shorter, say half a line?

2. I've also noticed that the second (last?) column of itemization seems
*never* to be longer that the previous ones, which seems to be quite
reasonable, but sometimes it would be better for it to be one line
longer than two lines shorter.  Is there a way of e.g. inserting a
manual column-break within multi-column itemizations and/or letting the
last column be longer?

Sorry people for being such a nuisance, but - as I've said - I use
itemizations a lot (mainly for different kinds of problem sets for
my students or my wife's pupils;)) and these issues appear quite often.
Also, I'd like to teach a bit of ConTeXt to my wife, who would like it
to *simply work* (she's great, but no TeX hacker;)).
