            The error is

            2018-05-16  2:26:08 140039501175040 [ERROR] Can't open shared library '/usr/lib64/mysql/plugin/ha_tokudb.so' (errno: 2, /lib64/libjemalloc.so.2: cannot allocate memory in static TLS block)

            This comes from the new jemalloc (see https://github.com/jemalloc/jemalloc/issues/937) when it's dlopen-ed or linked with a module that is dlopen-ed. Which is exactly our case, jemalloc is linked with tokudb, and tokudb is dlopen-ed.

            The fix: don't link TokuDB with jemalloc on FC28. Instead, let's LD_PRELOAD jemalloc when TokuDB is installed.
