[plt-scheme] current process id

I'm kinda new to the scheme mindset, so please would
someone tell me if this is preferable to writing an extension
module wrapping getpid().

Would this not lead to a more portable approach, since you'd
be forced to reimplement this properly for (say) Windows or
other system (such as HPUX) that doesn't implement "/proc"
(or similar).

Or am I thinking like a C programmer?
