I have a subsystem that populates a database from disparate data streams. 
It's been known to run for years without restarting, thanks to valgrind.

did you ever write a program which does heavy malloc()/free() 
on complicated (i.e., shared) data structures *and* runs for 
days, perhaps weeks? IMO it's very difficult to do this without 
a GC, and you have to exercise quite an amount of discipline 
to do it right.

Well, not exactly. Niklaus Wirth's Oberon kernel (around 1990) 
used a GC, and it did that quite efficiently.
