/* Maps a page of the request size near the text page that contains
* a symbol. Useful for hand-rolled JIT compilers to avoid indirect
* calls to symbols in a program on x86-64. (Part of the code here is
* a JIT compiler to encode JSON based on a struct descriptor, but it's
* not finished yet.)

* Thanks to Ole André V. Ravnås for the idea to use the NOREPLACE flag
* in mmap(), and to Paul Khuong for helping me make it more robust in
