#62 ZODB: Strange interference with os.popen

[kxroberto]

If I open a db/conn/storage, then make a os.popen to
completely unrelated dos-command, then try to close the
conn/db I get a strange lock permission:

----
z_conn=...

cmd=r'C:\bin\gnuplot\pgnuplot.exe'
g = os.popen(cmd, 'w')
global glob_file
glob_file=g
#glob_file=open('chart.txt')
#g.write('set data style linespoints'+'\n')
#g.flush()

z_conn.close()
z_db.close()
