That's not quite true. The man page for BRK(2) (at least on the Linux

In general, it is hard for any process to return the memory the OS allocate
to it back to the OS, short of exiting the whole process. The only case
that this works reliably is when the process allocates a chunk of memory by
mmap (which is chosen by libc if it malloc or calloc a large chunk of

If the memory usage is continually growing, you have something else
that is a problem -- something is holding onto objects. Even if Python is not
returning memory to the OS, it should be reusing the memory it has if objects

Whether it does or not depends on the OS, but as a general rule, you should

Btw, which Debian release are you running ?
If the system is set up correctly it should not be necessary to change env vars
to get it built.
I use Debian stable so "apt-get build-dep python2.7" doesn't work.

I understand that I/O in Python 3.0 was slower than 2.x (due to quite
a lot of the code being in Python rather than C, I gather), and that
this was fixed up in 3.1. So, io in 3.1 is faster than in 3.0.
