why slap_get_time()?

[Lawrence Greenfield <leg+@andrew.cmu.edu>]

I was talking to Mark Adamson today and he pointed out that there's a
slap_get_time() function that serializes calls to time().

I don't see any explanation for this in the code, not can I think of
why time() wouldn't be thread safe.

Is there something I don't know?
