As promised, here is a proof-of-concept patch to permit using either
fwrite+fsync or mmap+madvise+msync while writing files onto the file system
from a *.rpm package.
The patch passes "make check" (with the current known failures) on tip.
There are various switches to enable/disable the added functionality whose
usage should be fairly obvious. I have not bothered with either build/runtime
configuration with macros etc because its not yet clear whether msync(MS_ASYNC)
actually solves any problem yet.
If the proof-of-concept patch using msync(MS_ASYNC) does work, then we can
proceed from there.
