Yes, the linux client seems to behave the same. I guess it's because it caches
everything in memory, and does the write asynchronously, or at close()/fflush()
time. But it's broken anyway: close gets and error, but it's EIO not EDQUOT.
A NetBSD client reports the EDQUOT at write() time, I guess writes happens
more synchrounously here.
