+
+ On systems which provide /proc/loadavg (e.g., Linux), we use an idea
+ provided by Sven C. Dack <sven.c.dack@sky.com>: retrieve the current number
+ of processes the kernel is running and, if it's greater than the requested
+ load we don't allow another job to start. We allow a job to start with
+ equal processes since one of those will be for make itself, which will then
+ pause waiting for jobs to clear.
+
+ Otherwise, we obtain the system load average and compare that.
+
+ The system load average is only recomputed once every N (N>=1) seconds.
+ However, a very parallel make can easily start tens or even hundreds of
+ jobs in a second, which brings the system to its knees for a while until
+ that first batch of jobs clears out.
+
+ To avoid this we use a weighted algorithm to try to account for jobs which
+ have been started since the last second, and guess what the load average
+ would be now if it were computed.
+
+ This algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>,
+ based on load average being recomputed once per second, which is
+ (apparently) how Solaris operates. Linux recomputes only once every 5
+ seconds, but Linux is handled by the /proc/loadavg algorithm above.
