Comment (by gdt):

 I am trying to follow this and so far it looks like there is some subtle
 bug which has not been found.   If you do find behavior in NetBSD that you
 think is actually wrong please let me know.

 Another thing to keep in mind is that NetBSD has opencrypto(9) support
 (originally from OpenBSD, I think), which lets kernel crypto operations be
 offloaded to hardware coprocessors or other cpus.   There is also support
 for openssl(3) to do offload via a /dev node.    So in testing, one may
 want to disable that, as it's another source of complexity and possible
 bugs.

 Another thing would be to try to bisect the code path in the failing test
 to add intermediate checks, to try to find more precisely where the
 problem is happening.
