The PAC tests currently generate a very small number of false failures
since the limited size of PAC keys, especially with fewer bits allocated
for PAC due to larger VA, means collisions in generated PACs are
possible even if the PAC keys are different. The test tries to work around
this by testing repeatedly but doesn't iterate often enough to be
reliable.
We also fix a leak of file descriptors in the exec test which doesn't
matter now but can become an issue when the number of iterations is
increased, we can bump into limits on allocated file descriptors.
