// *** USE AT YOUR OWN RISK ***
// May Happen in Parallel (MHP) analysis by Lin Li.
// This code should be treated as beta-quality code.
// It was written in 2003, but not incorporated into Soot until 2006.
// As such, it may contain incorrect assumptions about the usage
// of certain Soot classes.
// Some portions of this MHP analysis have been quality-checked, and are
// now used by the Transactions toolkit.
