That's not my experience. Although both sorts of applications can be hard to debug and can have tricky race conditions, I find it easier to debug individual single-threaded processes even when they are part of a larger multi-process application. No doubt my debugging tools (typically GDB on GNU/Linux, for low-level C code) have influenced my experience.
