Serious/important:
- improve inline documentation strings - that's job for English native speakers
- resolve charset issues

- do something with those comments:
  // return string as-is, probably in some fancy encoding,
  // then user can call unicode(row[index], 'fancy-encoding', 'ignore')
  // to decode that
  
Moderate:
- fix apitest_mssql.py
- test on more platforms (especially big-endian ones)

Low priority:
- try to call dbexit() on module dealloc / python unload (how?)
