Build farm failure

dugong (icc on ia64) has been failing the contrib installcheck consistently
since 6 days ago with errors like:

ERROR: could not fsync segment 0 of relation 1663/40960/41403: No such file or directory

I checked a cvs diff between the two timestamps and that's precisely when the
self-adjusting bgwriter changes went in which knocked around bgwriter's
checkpoint logic quite a bit so it seems likely this is a real bug.

On the other hand it seems weird that it only occurs in contrib's check and
not the normal tests. And it also seems weird it only happens on icc ia64 and
not any other architecture under the sun. I installed icc on my machine (ia32)
but didn't get the same problem (we don't seem to have a recent icc ia32 build
farm member).

The only things I know about icc are that it likes to pad structs
unnecessarily and is picky about its -f arguments...
