BPL-250 Fudge for coverage bug

See nedbat/coveragepy#1012
& nedbat/coveragepy#1082

This bug in coverage results in an incorrect coverage
score by erroneously reporting lines of code as missing
from coverage. This commit artificially raised the coverage
over the threshold by having coverage ignore one of the parts
that it missed (which IS covered by unit tests).
