Pretty weird test, but it seems to survive on my Dual Core 1.5 GHz
laptop:

Create lots of devices:
  $ time (modprobe scsi_debug add_host\x16 max_luns2 num_tgts\x16 num_parts=2; udevadm settle)
  real	11m28.193s

23.000 block devices:
  $ find /sys/class/block/ | wc -l
  23824

72.000 sysfs devices:
  $ find /sys/ -name uevent | wc -l
  72224

We created 262 workers:
  $ ps afx | grep udevd | wc -l
  262

And 10 seconds later, all workers are gone:
  $ ps afx | grep udevd | wc -l
  2
