Comment (by komzpa):

 Cannot reproduce.

 Result I get:

 {{{
 POLYGON((-88.2059 41.7325,-88.206 41.7244,-88.1959 41.7241,-88.1959
 41.7326,-88.2059 41.7325),(-88.1997 41.7289,-88.1996 41.7285,-88.199
 41.7285,-88.199 41.7289,-88.1997 41.7289))
 }}}

 is expected, as your geometry is already below default 256 points. What
 are you using for rendering? May it happen interior ring is lost somewhere
 else in the process?
