How about using an optionally relative cache dir setting to let
the user decide ?
import imp, os
# Get cache dir, default to module_dir
cache_dir = os.environ.get('PYTHONCACHEDIR', '.')
# Get names and versions
module_cache_type = 'pyc'
module_cache_version = imp.get_magic().encode('hex')
module_name = module.__name__
module_cache_file = '%s.%s.%s' % (module_name, module_cache_version,
module_cache_type)
module_dir = os.path.split(module.__file__)[0]
# Determine cache dir and cache file pathname
module_cache_dir = os.path.abspath(os.path.join(module_dir, cache_dir))
module_cache_pathname = os.path.join(module_cache_dir, module_cache_file)
# Write PYC data to module_cache_pathname
