       buffer was in use at the time.  Change to a compile-time increase in the
       buffer size, when this authenticator is compiled into exim.
 
-JH/22 Taint checking: move to a hybrid approach for checking.  Previously, one
-      of two ways was used, depending on a build-time flag.  The fast method
-      relied on assumptions about the OS and libc malloc, which were known to
-      not hold for the BSD-derived platforms, and discovered to not hold for
-      32-bit Linux either.  In fact the glibc documentation describes cases
-      where these assumptions do not hold.  The new implementation tests for
-      the situation arising and actively switches over from fast to safe mode.
+JH/22 Taint-checking: move to safe-mode taint checking on all platforms.  The
+      previous fast-mode was untenable in the face of glibs using mmap to
+      support larger malloc requests.
