We do support 'make -j', yes. However, I don't think we support multiple instances of 'make' running in different build directories while sharing the same source directory just checked out from git. This is because the build process in this case will update some source files, and the different instances of 'make' can step on each others' toes. > * is there a known issue related to this? Not that I know of.
