Disabling it silently isn't ideal because some people may falsely
assume that their software is leak free.

In a typical setup (when /proc is mounted with nolinux), it doesn't
hang but prints some useful hints:

 $ ./a.out
 ==373==Can't open /proc/6440/task for reading.
 ==6440==LeakSanitizer has encountered a fatal error.
 ==6440==HINT: For debugging, try setting environment variable LSAN_OPTIONS=verbosity=1:log_threads=1
 ==6440==HINT: LeakSanitizer does not work under ptrace (strace, gdb, etc)

Can we add another hint here about detect_leaks?
