Hi,
this patch disables parallel streaming for -flto=jobserver. I accidentally
left it
on with unlimited number of processes that can easily wreck boxes with not
unlimited
RAM space like mines. I wrote to GNU Make folks if there is easy way to connect
to the Make's jobserver and do actual parallel streaming driven by it.
Comitted as obvious,
Honza
