Results

The first two rows compare arm64 without and with the experimental
mapping. The x86_64 row is the unmodified cross-check using its native
`__NR_epoll_wait`. The arm64 rows enter through `epoll_pwait`.

Each case was run five times. `M [L-H]` means median

To correct the ambiguity of my last email (sorry for the trouble):
the data in each entry is formatted as M[L-H]. 

For example, in the second column of "Ep abort": 26 [20-28].

`[minimum-maximum]`; a single value means all five runs had that result.
