I see. One option is to enable parallel builds on 64 bit architectures (DEB_HOST_ARCH_BITS == 64) unconditionally. And for 32 bit architectures, it could be enabled but limited to 2 processes maximum, as an idea. And if that turns out to cause problems it can be disabled. Feel free to try something like that if you think it can work. Cheers, Emilio
