+ * generic/tclZlib.c (Tcl_ZlibStreamGet): [Bug 3081008]: Ensure that
+ when a bytearray gets its internals entangled with zlib for more than
+ a passing moment, that bytearray will never be shimmered away. This
+ increases the amount of copying but is simple to get right, which is a
+ reasonable trade-off.
+
+ * generic/tclStringObj.c (Tcl_AppendObjToObj): Added some special
+ cases so that most of the time when you build up a bytearray by
+ appending, it actually ends up being a bytearray rather than
+ shimmering back and forth to string.
+
+ * tests/http11.test (check_crc): Use a simpler way to express the
+ functionality of this procedure.
+
* generic/tclZlib.c: Purge code that wrote to the object returned by
Tcl_GetObjResult, as we don't want to do that anti-pattern no more.
