Re: [exim] 4.87 -> 4.88 readconf performance

With the 555 calls of macro_create() it does seem that the
builtin macros are being activated. The place that happens
is probably the call to macros_create_builtin() in
get_config_line() - about line 1029 of readconf.c in
master HEAD. There's a commented-out printf on the line
before; please uncomment that and run that build
(normal debug facilities don't work this early in Exim's
startup, unfortunately).

We should discover what the trigger is.
