> Then mmap it once writable to edit the JIT code; when you're finished, mmap it execable instead.
Here comes the first question: PCRE-JIT support multithreading, where one
thread can compile a new JIT code while another thread executes a compiled JIT
code. If I cannot map it as both writable and executable, how can I handle it?
If it is not possible, I need to allocate 4K aligned spaces for all compiled
patterns, which wastes memory, but writing and executing can be separated. And
that does not even need any temporary files.
