No. What I understand from the above ticket, is that the problem is
in the "libsandbox".

Quote: "Also noticable on openvz guests, where getcwd test takes
about minute and without sandbox its below 3s."

Quote: "The underlying problem appears to be that libsandbox's
mkdir() scales very poorly."

Quote: "The slowness comes from glibc own getcwd calls. But this
isn't a problem when running outside sandbox ..."

etc.
