High memory usage - program mistake or Python feature?

Woops, I forgot the important part of the regular expression, that should be

cmd_res = dict(zip(cmds, [re.compile(' Log \w+: %s " % (x)) for x in cmds]))

or if you don't prefer lambdas (I do, largely from pre-python baggage)

cmd_res = dict(zip(cmds, map(lambda x:re.compile(' Log \w+: %s " % (x)), cmds)))

but now that line is getting long and busy, better to do

cmd_raw_res = [re.compile(' Log \w+: %s " % (x)) for x in cmds]
cmd_res = dict(zip(cmds, cmd_raw_res))
