dev-qt/qtwebengine consumes a lot of memory during build, which seems to be caused by it using the jumbo build feature of Chromium (I see it building ..._jumbo_N.c files, which for www-client/chromium is being triggered by USE=jumbo-build). In fact it consumes so much memory, that I cannot build it in tmpfs with 16G of RAM. Would it be possible to allow users to disable the jumbo build feature through a IUSE=jumbo-build flag?
