> Hint: Wasm lacks an MMU, meaning that Linux needs to be built in a NOMMU configuration. Wasm programs thus need to be built using -fPIC/-shared. Alternatively, existing Wasm programs can run together with a proxy that does syscalls towards the kernel. In such a case, each thread that wishes to independently execute syscalls should map to a thread in the proxy. The drawback of such an approach is that memory cannot be mapped and s
