+Subject: configure: Add support for tcmalloc
+From: Fam Zheng <famz@redhat.com>

+
+This adds "--enable-tcmalloc" and "--disable-tcmalloc" to allow linking
+to libtcmalloc from gperftools.
+
+tcmalloc is a malloc implementation that works well with threads and is
+fast, so it is good for performance.
+
+It is disabled by default, because the MALLOC_PERTURB_ flag we use in
+tests doesn't work with tcmalloc. However we can enable tcmalloc
+specific heap checker and profilers later.
+
+An IOPS gain can be observed with virtio-blk-dataplane, other parts of
+QEMU will directly benefit from it as well:
