Hi Warner,

Several users have been running their systems with the updated jemalloc for a 
while now. I've been running my systems, a dual-socket NUMA workstation and a 
laptop (both x86_64), for over a year without issues.

May I suggest importing the updated jemalloc into 15-CURRENT for wider testing? 
It's better to have it in the tree for a longer period of time before the 15.0 
release.
Sorry for the noise and thanks.
