@ -141,6 +141,10 @@ any of the following arguments (not a definitive list) to 'configure':
--disable-experimental
Disable support for the experimental API (*allocm()).
--disable-zone-allocator
Disable zone allocator for Darwin. This means jemalloc won't be hooked as
the default allocator on OSX/iOS.
--enable-utrace
Enable utrace(2)-based allocation tracing. This feature is not broadly
portable (FreeBSD has it, but Linux and OS X do not).
