Yes, you found a bug. You can use PyTables 2.2b2 (recently announced) where
this is solved:
>>> import tables
>>> file1=tables.openFile('file.h5','r')
>>> file2=tables.openFile('file.h5','r')
>>> file3=tables.openFile('file.h5','r')
>>> file3.close()
>>> file1
<closed File>
PyTables 2.2b2 passes all the know tests and should be fairly safe to use (it
is in beta stage mainly because the new API additions for supporting links
need some time before freezing definitely).
Hope this helps,
