@ -157,9 +157,6 @@ any of the following arguments (not a definitive list) to 'configure':
--disable-valgrind
Disable support for Valgrind.
--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.
