In doing some other research https://github.com/llvm/llvm-project/issues/189711 I found that the only way gdb and gdbserver gets memory information is reading `/proc/pid/maps` using `vFile` packets.

So I suspect they will switch to reading `/proc/pid/smaps` instead, which is a superset of `maps`. Which is what we do, we just have lldb-server do that and put the information into `qMemoryRegionInfo` responses.
