New patch, clean fix.
Answer to comment #18, Thomas, the flush is needed for streamio_12.f90 where we
use a write(10, pos=1) to reposition the file somewhere far from the current
buffer contents.
Status since comment#24. Two regressions have led me to back away and take a
different approach. I would still like to revisit the unix.c internals later.
For now, the attached patch gives the very substantial improvements in STREAM
i/o and regression tested OK on x86-64. The patch is simple and well
contained.
I will post some benchmarks shortly and submit to list for approval.
