Platform notes and implementation details

Windows

In order to provide some functionality resusage dynamically loads the following libraries at startup:

  1. Psapi.dll to get memory (physical and virtual) used by specific process.
  2. Pdh.dll to calculate CPU time used by system.

If specific library could be loaded, corresponding functions will always throw WindowsException.
