2.6.29.1 to 2.6.30rc1 upgrade breaks my hotplug (and how I fixed it)

Someone changed

To do stuff more parallel,

       }

This breaks my hotplug, it only gets called once about every 500 events.
Changing UMH_NO_WAIT back to UMH_WAIT_EXEC again fixed my hotplug problems.

I used i686 kernel with /sbin/mdev handler (busybox system)
gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)
