Pandas Bug : HDFStore is still locked after closing the file

Code Sample, a copy-pastable example if possible

After running this code :

store.append(tablename, df_i, format=format, complib=complib)
store.close(); del store

Problem description

I cannot delete/move the windows h5 store file, it is still locked by Python.exe

Expected Output

We expect the file being release.

Output of pd.show_versions()

pandas: 0.18.1

pandas: 0.18.1

Comment From: jreback

looks ok to me.

In [22]: df = tm.makeDataFrame()

In [23]: store = pd.HDFStore('foo.h5')

In [24]: store.append('df', df)

In [25]: store.close()

In [26]: del store
