The same with userland utils. Huh? Very few applications use pipes, but *lots* (most) of the applications use malloc, so using simple math the chances of a serious bug occuring because of phk-malloc will be greater than bugs found with pipes. Now, given the amount of time that phk-malloc has had to get beat on in -current it's unlikely that real obvious bugs still exist, but there is still a chance. > And who forbids you, in case things are going wrong in > -stable snapshots (they're experimental, anyway), > replace phk malloc back with todays one? That goes against the grain of -stable. That's what -current is for. :) Nate
