The ACL on the per-user hsperfdata_<user> directory have been observed
to cause administration problems on some systems. At least one system
administrator encounted problems on some machines when trying to delete
accounts that contained the hsperfdata_<user> directory. The files under
the directory were able to be removed by a user with Administrator privileges,
but the directory itself could not. The administrator had to log into the
system as the end user and modify the ACL with the cacls command in order
to remove the directory. The ACLs on the dirtectory should be set up such
that users with administrator privileges have the rights to delete the
directory.
