Comment (by mmcc):
Conveniently, kdump gives the return value of system calls in the
following form:
{{{
17991 tor CALL gettimeofday(0x34ee15caca0,0)
17991 tor STRU struct timeval { 1420077862.124873 }
17991 tor RET gettimeofday 0
}}}
As you can see, the value in the struct is the Unix timestamp, as you
would expect.
The kdump I had included all system calls from the second 1420077863, so I
grepped and wc -l'ed those. There were 6,974 instances, which implies that
the Tor process made 6,974 calls to `gettimeofday()` in a second.
