With some Linux archs and revisions, this function is available via (low 
latency/low overhead) vDSO calls.

Unfortunately there seem to be arch where an "independent" (e.g. 
monotonic)  timing clock can't be provided and in fact vDSO seem not to 
be "ubiquitous enough" (nor really decently on the enhancement agenda of 
the Linux Kernel Team) for trying to use it with a would-be multi-arch 
library (i.e. any commonly usable library for fpc/Lazarus).

I did some successful experiments with vDSO in fpc, hoping to be able to 
improve EpikTimer, but gave up due to the said facts.
