Summary: all connections are in use
Initial Comment:
Opening and closing a connections in a loop fails because a temporary file is
not closed.
Adding in the close, shown below, fixes this.
if sys.platform == 'win32':
baseNameSpaceEnv["close"](tmp)
baseNameSpaceEnv["unlink"](tfile)

Message:
Sorry. I didn't give you enough information. It's windows only. The details
windows install creates this file:
C:\Python25\Lib\site-packages\rpy2\robjects\__init__.py
If you look at the block beginning at line 133 you can see the problem. If
sys.platform == 'win32' the code will unlink, but *not* close the file. To
expose the bug, put a print statement in a loop which reaches this code. If
the loop is large enough it will crash because the file is not closing.
Simply adding baseNameSpaceEnv["close"](tmp) to the block will fix the
problem.

If this is a bug, how to trigger it as well as which part of the current
code you are proposing to fix is necessary.
Without it, I am not quite sure to follow you.

I think it's a bug because the connection should be closed. If the
connection is in a loop it will eventually crash because rpy2 does not
close the file, but repeatedly opens it. If rpy2 closes the file, which I
think it should, the crash does not occur.

Thanks for your report, but is this a bug in rpy2 or a programming hint for
win32 programmers ?
