Hi,

I compiled and ran the code but changed 1000 to 10000 in the for
loop. I noticed that when ru_stime reached 22002 it stopped counting and 
ru_utime started counting.

ru_utime: 0.000000
ru_stime: 0.021813
*****************************************
ru_utime: 0.000000
ru_stime: 0.022002
*****************************************
ru_utime: 0.000200
ru_stime: 0.022002
*****************************************
ru_utime: 0.000393
ru_stime: 0.022002

I don't know the first thing about getrusage but maybe it will mean something
to someone else.

It takes longer to glue a vase together than to
