running tests from make causes spurious repo changes

[Jonathan Gibbons]

Erik,

It could be a feature of the build (i.e. test makefiles) to verify that 
no source-controlled files were modified in the course of a test run.

A related, secondary feature could be to make sure that no new files 
were written in directories containing source-controlled files (i.e. 
src, make, test, etc). Together, these checks could be combined by 
comparing the output of "hg status" before and after the test run.

Martin's suggestion to run on a read-only filesystem is also a good one, 
but maybe harder for most people to set up (e.g. on a laptop or Dev 
machine), so makefile checks would be nice.
