Disadvantages of eliminating syscalls in Singularity

I have just discovered the strace utility, the ApiSpy for linux. It turned out to be extremely useful for identifying problems with make (you know this huge build process, with no debugging). With the facility, we easily differenced the invocation sequence between successful and failed builds. Now, recording the system of this will not be possible if the user-kernel boundary is distributed.
