commit 6ff3c31888e614d1f6f78449e41d293612a855be

    Fix documentation bug: TSOs are *not* unconditionally kept on the mutable list.
    
    The bug where TSOs were unconditionally kept on the mutable list was #1589
    which was fixed in 04cddd339c000df6d02c90ce59dbffa58d2fe166.
    Curiously enough, the commit that changed this comment
    0417404f5d1230c9d291ea9f73e2831121c8ec99 occurred *after* this
    change was made; I can only assume Simon Marlow accidentally forgot
    that he had fixed this bug. :-)
