+Routine Description:
+
+    This routine creates a thread that will later be used to execute
+    16 bit application instructions.  The parameters and end results
+    are the same as the Win 32 CreateThread function.  This function
+    allows the IEU to take appropriate action on thread creation.
+
+Arguments:
+
+    lpThreadAttributes -- Supplies the security attributes for the thread
+    dwStackSize -- Supplies the size fo the threads stack
+    lpStartAddress -- Supplies the starting address for the thread
+    lpParameter -- Supplies a parameter to the thread
+    dwCreationFlags -- Supplies flags that control the creation of the thread
+    lpThreadId -- Returns the Id of the thread
+
+Return Value:
+
+    A handle to the thread if successful,
+    0 otherwise.
