I'm now writing pthread support patch set and it will naturally
include pread/pwrite like this patch set.

It sounds to me that using pread/pwrite only to reduce lseek code is
weak in motivation. Is there another visible merit? For example, any
kind of performance improvement. I guess it's small even if exists
compared to I/O.
