remove most shell out-calls in clam

[Fred T. Hamster]

reduce these to a minimum since they hose up on windows. windoze seems geared towards running huge apps and apparently it does not support having a small app to start, run, and exit in quick order like on linux.

this is really rough though; we use these calls a lot.

these are the kinds of things that should be gathered before running anything!
it could be part of the feisty setup.
