Setiathome _is_ running at nice +19... The H6 version cured the 2.4.17 boot
problem here. Here are some numbers (H6) for you to consider:
make bzImage with setiathome running nice +19
make bzImage 391.11s user 30.85s system 62% cpu 11:17.37 total
make bzImage alone
make bzImage 397.33s user 32.14s system 92% cpu 7:43.58 total
Notice the large difference in run times...
System is: UP K6-III 400, 512M
