Is there a reason why uses of bzero() should be changed to memset()?

I've always found memset usage more error-prone; every so often, I
find myself setting a random value to zero bytes, i.e.,
memset(ptr, size, 0), which the compiler doesn't pick up.
I'm not sure about the size/speed tradeoffs in inlined versions of
memset() vs. bzero() either; then again I've never seen either function
show up in a runtime profile, so this doesn't concern me.
