Instrumentation support is here! You can enable ASAN with ./configure --enable-asan, TSAN with --enable-tsan, and UBSAN with --enable-ubsan.
Note that TSAN has issues on some Linux kernel/gcc combinations.
See this link: http://llvm.org/viewvc/llvm-project?view=revision&revision=282152
(TSAN needs a 64bit compile and also GCC 5.x or newer than 6.2 :/ )
