Under 5.2-BETA, if I run a program with "env MALLOC_OPTIONS=j" then all
the malloc()'ed memory will be zeroed even though I did not ask for it
(by specifying "Z"). Also, "J" (memset to 0xd0) even appears to run a
somewhat *faster* than "j". Why doesn't "jz" return uninitialized memory
and isn't the fastest of {jz,J,Z} (where J is the fastest)? I'm new to
FreeBSD so I don't know if previously this worked as documented in
malloc(3).
TIA
