//--------------------------------------------------------------------
-// PURPOSE: This module deals with management of the entire process
-// address space. Almost everything depends upon it, including dynamic
-// memory management. Hence this module is almost completely
-// standalone; the only module it uses is m_debuglog. DO NOT CHANGE
-// THIS.
+// PURPOSE: This module contains the inner loop of the execution
+// mechanism, which is: find next basic block, execute it, repeat until
+// the next bb isn't found in the fast-cache; or if the current bb
+// exited with a request for some special action before continuing; or
+// if the current thread has used up its scheduling quantum.
