+    * (iounit)".  In fact, the Twrite header is only 23 bytes

+    * tag[2] count[4]"), so "24" appears to be the size of the Twrite
+    * header rounded up to a nice round number.
+    *
+    * In older versions of 9P ("9P1"), the max message size was
+    * defined as part of the protocol specification rather than
+    * negotiated.  In Plan 9 1e it was (8*1024)+128, and was bumped to
