Something is broken in their ppc system: apparently, they allow the mknod
syscall to exit without an error in cases where is must fail with EEXIST
because the target file already exists.  This violates the contract:
"If pathname already exists, or is a symbolic link, this call fails with
an EEXIST error."  I suppose they use some kind of mknod interception,
and it doesn't implement the expected semantics.

We can either come up with a workaround or report a bug and let them fix it.

Could you add some diagnostics to the test, e.g. how much time did it take
in the first and in the second case?  This way we could see what's going

I'd rather keep the test to be sure the pidns cache is actually tested.
