This is not a critical problem, just an observation.
'winetricks psdk2003' works today, but seems a little slow.
It spends about five minutes thinking, then about half an hour (?) copying.
oprofile shows that during the thinking phase, 
cpu time is divided up almost evenly between msi.dll and libwine.dll:
   213762 52.2918 msi.dll.so
   173435 42.4267 libwine.so.1.0
    16658  4.0750 kernel32.dll.so
During this time, cpu time inside msi is divided up like this
67832    31.7325  JOIN_fetch_int
33596    15.7165  WHERE_evaluate
28618    13.3878  read_table_int
22133    10.3540  TABLE_fetch_int
14115     6.6031  STRING_evaluate
13322     6.2322  bytes_per_column
and cpu time inside libwine is divided up like this:
152497   87.9275  strlenW
12290     7.0862  compare_unicode_weights

During the copying phase, cpu time is mostly in the kernel:
    23340 37.7866 no-vmlinux
    15967 25.8500 cabinet.dll.so
     5469  8.8541 libwine.so.1.0
Of the 1/4 of the cpu time in cabinet.dll, nearly all of it was in one
function:
15299    95.8164  LZXfdi_decomp

These numbers are with -O0, so they're not especially useful
for predicting normal speeds.  It'd be interesting to see where the
cpu time is at -O2.
