I still don't understand exactly what the effects are on test coverage.

Could you provide a list of all the functions tested in 
tst-cancel-wrappers.sh, with, for each function, a statement either of the 
other testcase that tests cancellation of that function, or of why it is 
not possible to test cancellation of that function in a useful way?
