From: Peter Marko <peter.ma...@siemens.com>
Set GRPC_PYTHON_BUILD_EXT_COMPILER_JOBS to limit spawned compiler
processes. Without this it uses all available CPUs (via
multiprocessing.cpu_count()) and can exhaust build host since there are
lot of files to compile (e.g. with 128 cores it manages to spawn 128 gcc
processes)
Note that this is a general problem for all setuptools based builds with
build_ext compilation which can either compile with 1 thread or
cpu_count threads. grpcio hot-patches setuptools and allows to set
specific build concurrency value.
