cvs commit: ports UPDATING ports/lang/python24 Makefile ports/lang/python25 Makefile ports/lang/python26 Makefile ports/lang/python27 Makefile ports/lang/python31 Makefile ports/lang/python32 Makefile

[Li-Wen Hsu]

It's the default stack size of the system it runs on.  If you don't set
THREAD_STACK_SIZE while building python, it will be defined to 0.  When
running, python will skip calling pthread_attr_setstacksize(), and
pthread_create() will use the system's default value: 2MB on amd64 and
1MB on i386.

But in python27+, if there is no THREAD_STACK_SIZE defined by user when
building, it will be hard-coded to 0x400000 (4MB) on FreeBSD.  It is
because our default stack size for new threads is too small. [1]

Anyway, now all the values are larger or equal than the original size
we defined in ports: 128K or 1MB (with HUGE_STACK_SIZE).  I think
it is right way for nowadays.  There are some users reported about small
stack size causes problems for complex applications like Django. [2]
