Hello,
qtwebkit currently puts hurd buildds on their knees because its
build systems uses "make -j", i.e. without specifying the requested
parallelism level, which means unbound parallelism, which when building
c++ code basically means filling dozens of gigabytes of memory.
This apparently comes from ./Tools/Scripts/webkitdirs.pm which for
unknown platforms makes numberOfCPUs() return an empty string, which
thus ends up with "make -j".
The attached patch makes qtwebkit default to 1 instead of defaulting to
unbound parallelism.
Perhaps upstream will also prefer to try to use the portable way,
sysconf(_SC_NPROCESSORS_ONLN) (I don't know the perl equivalent).
