including child processes in coverage numbers?

I was all excited that the //pm option in ncover 1.5.8 would track the coverage numbers of a child process in *addition* to the coverage it was providing for the assembly it was initially loading, e.g.

c:\> ncover.console.exe nunit-console.exe fxtest.dll //pm testapp.exe

However, it seems that it *only* tracks the coverage numbers of testapp.exe (and then only the first time it's run). My fxtest.dll runs a bunch of tests that don't involve testapp.exe and then also starts testapp.exe a few times. How do I get combined coverage numbers for what's executed directly in fxtest.dll *and* *all* of the times that testapp.exe runs? Thanks!
