No.  That is fine.  gps_waiting() returns when there is data available.

As the doc clearly says:

    "gps_waiting() can be used to check whether there is new data from
    the daemon. The second argument is the maximum amount of time to
    wait (in microseconds) on input before returning.  It returns true
    if there is input waiting, false on timeout (no data waiting) or
    error condition."

So 2000 is the MAX time to wait, which is fine.

No.  The problem is the uninterruptible sleep(1).  Which is why that
is the part of the code I highlighted.
