>Description:

getrusage does not appear to get valid values for some fields,
for example, the test program included below retreived these
values for itself:

r = 0
ru_utime.tv_sec = 0
ru_utime.tv_usec = 0
ru_stime.tv_sec = 0
ru_stime.tv_usec = 0
ru_maxrss = 0
ru_ixrss = 0
ru_idrss = 0
ru_isrss = 0
ru_minflt = 67
ru_majflt = 0
ru_nswap = 0
ru_inblock = 1
ru_oublock = 1
ru_msgsnd = 0
ru_msgrcv = 0
ru_nsignals = 0
ru_nvcsw = 2
ru_nivcsw = 0

 This ticket is really old. What were some of the invalid values (from 
 the original ticket)?

 Here is my output today from this test:

 r = 0
 ru_utime.tv_sec = 0
 ru_utime.tv_usec = 655
 ru_stime.tv_sec = 0
 ru_stime.tv_usec = 655
 ru_maxrss = 7744
 ru_ixrss = 8
 ru_idrss = 4
 ru_isrss = 12
 ru_minflt = 169
 ru_majflt = 0
 ru_nswap = 0
 ru_inblock = 0
 ru_oublock = 0
 ru_msgsnd = 0
 ru_msgrcv = 0
 ru_nsignals = 0
 ru_nvcsw = 0
 ru_nivcsw = 0

 I don't remember exactly.  I suspect I was doing some profiling
 and looking at time and memory stats.  I think it's fine to close this.
