Funny, I reduced it to more or less the same thing, except the other way
'round: I suspected exceptions to be the source of the leak, so I kept
adding more complicated exception processing to my leak-test until it
started leaking; it started leaking the moment I added a doctest to it, but
not before. I somewhat doubt it's directly related to exceptions, though.

Michael Hudson also mentioned it on #nfs, and it seems he went a little

00:54 <mwh> i found that test.test_support.check_syntax reliably leaks 5
00:55 <mwh> as does compile('1=1', '', 'exec') in fact
00:58 <mwh> it's leaking a tuple containing two Nones a string and an int, i
01:00 <mwh> oh well, i guess sean and richard know what they changed...

Does 'a tuple containing two Nones, a string and an int' ring a bell to
anyone? :)
