==========================

repoze.filesafe provides utilities methods to handle creation
of files on the filesystem safely by integrating with the ZODB package's
transaction manager.  It can be used in combination with repoze.tm (or
repoze.tm2) for use in WSGI environments.

Permanent ERRNO 18

This is probably me not knowing how to use filesafe but I have been unable to google a good answer and the problem seems easily reproducible:

using Pyramid:

  $ paster pshell test.ini -p python
  Python 2.7.2 (default, Oct 14 2011, 23:34:02) 
  [GCC 4.5.2] on linux2
  Type "help" for more information.

  Environment:
  app          The WSGI application.
  registry     Active Pyramid registry.
  request      Active request object.
  root         Root of the default resource tree.
  root_factory Default root factory used to create `root`.

  Custom Variables:
  mod          smd.models
  s            smd.models.S
  t            transaction

  >>> from repoze.filesafe import create_file
  >>> f = create_file('hello_world', 'wb')
  >>> f.write('hola mundo, esto es una prueba')
  >>> f.close()
  >>> t.commit()
