[metapost] problem with 'dvips mproof'

when processing a file s.mp containing the lines
prologues := 3;
tex mproof s.1
I have difficulties watching the resulting file mproof.ps in GSview or
PS_View (remember, this is dvips output). Symptoms are different for
different values of variable prologues.
0 - The files looks fine with text "test" probably rendered in
1 - Fine again. But at closer inspection the kerning between
letters changes slightly in comparison to prologues:=0.
2 - Exactly the same as with prologues:=1.
3 - The text is visible, but rendered with something else than
CMR (probably Courier).
Results with GSview are similar, with one notable exception. With
prologues:=1, the text "test" is not rendered at all. With
prologues:=3, "test" is also rendered in Courier. Due to slow redrawing
in GSview I cannot see if kerning changes between prologues=0 and 2.
As an additional observation that is possibly related, if TeX output is
converted to pdf via
dvipdfm ends with a message
> ** WARNING ** 6 memory objects still allocated
if prologues is set to 2 or 3.
Since this is not about previewing MetaPost output, but PostScript
generated by dvips, I had expected no issues other that differences in
file size for varying values of prologues possibly. Is this a bug in
mpost or dvips or is it expected behaviour?
