} Also might be worth checking whether the

I set HAVE_MMAP 0 in config.h, recompiled, and compared on my CentOS VM;
there is no significant difference in string test:

Running [zsh-noMMAP]:                    string_test      26612.85
Running [zsh-36926]:                     string_test      26688.94

Function test is actually slightly worse:

Running [zsh-noMMAP]:                    function_test    28053.23
Running [zsh-36926]:                     function_test    27759.94

No significant diff in the other tests either.  So currently this only
seems to apply to MacOS.
