Running xsd.exe with the following schema hangs indefinitely, showily growing
in memory consumption (leak?)

I ran it on Windows 7 x64, with this command (with all the proper paths to
avoid accidentally calling windows versions)

mono xsd.exe circularGroups.xsd /c

<?xml version="1.0" encoding="utf-8"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified"

  <xs:element name="elem1">
      <xs:group ref="t:grp1" />

  <xs:group name="grp1">
      <xs:group ref="t:grp2" />

  <xs:group name="grp2">
      <xs:element minOccurs="0" name="elem2">
          <xs:group ref="t:grp1" />
