executable. It makes perfectly sense in the general case, but we need
to circumvent this rule of thumb in our case. To that extend, the
binary is copied in a temporary file before being re-linked against.
+`dlmopen()` cannot be used as it only allows 256 contextes, and as it

This approach greatly speeds up the context switching, down to about
40 CPU cycles with our raw contextes, instead of requesting several
before dl-loading them to remove the code and constants, and mmap
these area onto a unique copy. If done correctly, this would reduce
the disk- and memory- usage to the bare minimum, and would also reduce
-the pressure on the CPU instruction cache.\n

Also, currently, only the binary is copied and dlopen-ed for each MPI
rank. We could probably extend this to external dependencies, but for
