 To Find The ASAN Memory Limit: (64-bit only)
 
-On 64-bit platforms, afl needs to know how much memory ASAN uses.
-Or, you can configure tor without --enable-expensive-hardening, then use
-  make fuzz
-to run the generated test cases through an ASAN-enabled fuzz-http.
+On 64-bit platforms, afl needs to know how much memory ASAN uses,
+because ASAN tends to allocate a ridiculous amount of virtual memory,
+and then not actually use it.

   the fuzzing harness will hang when the memory limit is too small.)
