The root of this issue is in sysfs directory creation. Every time
a directory is created a string compare is done against sibling
directories ( see sysfs_find_dirent() ) to ensure we do not create 
duplicates.  The list of directory nodes in sysfs is kept as an
unsorted list which results in this being an exponentially longer
operation as the number of directories are created.

Again, are you sure about this?  I thought we resolved this issue in the
past, but you were going to check it.  Did you?
