           Summary: Process PerformanceCounters broken
    Classification: Mono
           Product: Mono: Runtime
           Version: 2.4.x
          Platform: x86-64

When sampling the "% User Time" performance counter for a process outside the
mono runtime, all values are reported as zero.

Reproducible: Always

Steps to Reproduce:
1. Run sample app to query processor usage for a process
2. Compare with top
3.
Actual Results:  
reports zero

Expected Results:  
Some value similar to top

This patch seems to work for me
