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.
