For compiling, use a temporary directory that is inside the part location 

We want to keep the build directory when keep-compile-dir=true,
whereas sharing a part is reliable only if everything goes inside
the same directory.

Error: System error
But we had a bug with version v0.11 is that if build was interrupted in the middle of the build of a
shared part. The shared part was left in an inconsistent state that looked like installation succeeded.
Let's simulate a scenario where buildout is terminated in the middle of a build.
For this, we need a package that takes a lot of time to install.
>>> with tarfile.open(package_path, 'w:gz') as tar:
... configure = b'#!/bin/sh\necho configure started\nsleep 300;'
... info = tarfile.TarInfo('configure')
... info.size = len(configure)
... info.mode = 0o755
... tar.addfile(info, BytesIO(configure))
We also need a bit more complex method to run buildout so that we send a termination signal in the
middle of build process.
>>> import signal
>>> import time
>>> buildout_process = subprocess.Popen(buildout, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
>>> output_line = ''
>>> for _ in range(10):
... time.sleep(1)
... output_line = buildout_process.stdout.readline()
... if output_line and b'configure started' in output_line:
... print ('configure started')
... buildout_process.send_signal(signal.SIGKILL)
... print ('buildout terminated')
... break
configure started
buildout terminated
>>> _ = buildout_process.wait()
If we run buildout again, the compile dir is removed again and installation is retried. This time
installation can succeed.
This was not the case in version 0.11 of this recipe. If installation of a shared part failed, this was
not detected and the part was considered as installed.

If ``shared-part-list`` is set as an option in buildout section and
``shared`` is True, package will be installed in shared_part/package
and a hash of the recipe's configuration options.
There can be multiple path listed in ``shared-part-list``, the recipe
will look in each of these paths if package was already installed and
if not, it will install the package in the last entry the last entry
from the list of ``shared-part-list``.
if not, it will install the package in the last entry.
If package was already installed in any of the ``shared-part-list`` used, it will be
used instead of installing if one package has been installed.
