New issue 2268: _sqlite3.OperationalError: disk I/O error
https://bitbucket.org/pypy/pypy/issues/2268/_sqlite3operationalerror-disk-i-o-error
Valentin Lorentz:
When running my code on Travis CI, I get the following traceback:
```
#!python

The above exception was the direct cause of the following exception:

sqlalchemy.exc.OperationalError: (_sqlite3.OperationalError) disk I/O error
[SQL: '\nCREATE TABLE requests (\n\trequest_handling_start_time FLOAT,
\n\trequest_handling_end_time FLOAT, \n\trequest_answers_json TEXT\n)\n\n']
```
I believe this code should be enough to reproduce the issue:
```
#!python
import sqlalchemy, tempfile
metadata = sqlalchemy.MetaData()
requests = sqlalchemy.Table('requests', metadata,
sqlalchemy.Column('request_handling_start_time', sqlalchemy.Float),
sqlalchemy.Column('request_handling_end_time', sqlalchemy.Float),
sqlalchemy.Column('request_answers_json', sqlalchemy.Text))
with tempfile.NamedTemporaryFile('w+') as fd:
uri = 'sqlite:///%s' % fd.name
engine = sqlalchemy.create_engine(uri)
metadata.create_all(engine)
```
However, I am not able to reproduce it outside Travis.
