These bugs result in gradual slowdown of indefinitely-running scripts which

these bugs are considered honest-to-goodness "memory leaks" by valgrind
seems unimportant.

google-perftools is able to help analyze such problems.
It can produce memory reports in certain intervals of the program lifetime, and they graphically show who owns how much memory at particular times.

In a nutshell, the run is done like this:
HEAPPROFILE=google-profile-pid$$ LD_PRELOAD=/usr/lib/libtcmalloc.so $*
