if libuuid was present on the system, python would link with it in:
lib/python3.9/lib-dynload/_uuid.cpython-39-x86_64-linux-gnu.so

if libtinfo was present on the system, readline would prefer to use it instead of libncurses

This will let a non-shared Theia (for example coming from shacache
binary) to be able to use the shared parts of a machine.

This reverts commit 31eaaec1a2bd8bc8648a686a83be989a9615a93e.

This slows down business template by a factor of two and it seems we
don't need it. I'm experimenting with hacks in ppml.py but maybe just
creating the Unpickler with encoding='utf-8' in
product/ERP5Type/XMLExportImport/__init__.py:267 is enough ?

at this point they all fail after long timeouts, because neo does not
support py3 yet

see 2a457867 (erp5: Rework testrunner's HTTP server, 2018-09-04), with
python3 the timing is not same and sometimes the parameter was not
propagated before root partitions promise were all solved, this add a
promise at the root partition to ensure the parameter is propagated

this promise should be enabled regardless of test runner configuration

Not sure why it was OK on python2 and not sure if this has to be done
or the promise code needs to cast the results of getConfig()

Otherwise it fails with the following exception because of non-ASCII characters
(`[A-Z&é@{]{3,7})`) (see unconvert()) below):
