I don't think it would be as problematic upon application startup as during runtime (for example, looking to see whether a file's appeared every 100ms).

Importance of application startup

One dose of 'powertop' or other profiler will find the "sore thumb" applications or usages that poll; but these are rare. Over half of all processes run for 0.1 CPU seconds or less, and for these the "startup" consumes the vast majority of resources. A shell with builtin busybox (mv, ln, cp, rm, date, ls, ...) can be a significant savings. The general case would be a learning shell that could identify and remember the state after startup of a large class of frequently-run applications.
