Funny thing is, .rsp stays there if compilation is successful, and
gets deleted automatically by bjam if compilation fails - the opposite
of the desired behavior.

Today I tried to build on Windows a project that is normally built on
different UNIX flavors. This .rsp file issue is very annoying - it's
nearly impossible to debug build issues not being able to see the
command line. As a workaround, I added 
copy "$(<[3]:W)" "$(<[3]:W).saved"
in msvc.actions.link and msvc.actions.compile. At least I can see the
rest of the command line in .rsp.saved, and even can re-run failed
actions after manually renaming .rsp.saved to .rsp

I guess the solution would be to exclude .rsp file from source target
list before any of msvc.actions.* called
