 27.  As of Python 2.4, the mpz, rotor and xreadlines modules have been 
 dropped from the Python source tree.
+28.  The subprocess module was added to the standard library relatively
+late in the 2.4 development cycle.  Unfortunately I haven't had the
+round tuits to adapt the module to the EMX environment yet, and
+test_subprocess has a number of failures as a result.
+29.  The default stack size for threads has been 64k.  This is proving
+insufficient for some codebases, such as Zope.  The thread stack size
+still defaults to 64k, but this can now be increased by defining
+THREAD_STACK_SIZE to an appropriate value in the Makefile (which contains
+a commented out definition for 128kB thread stacks).  I have seen
+references to heavy Zope/Plone usage requiring 1MB thread stacks on
+FreeBSD and Linux, but doubt that for most likely usage on OS/2 that
+more than 256kB is necessary.  The size of the required stacks (main 
+and thread) can vary significantly depending on which version of gcc
+is used along with the compiler optimisations selected.
