TestMemNodeFsBasic: Size after write incorrect: got 0 want 1

[navytux]

( This is probably due to the same reason as #479. Still filing for information not to get lost )

I'm getting TestMemNodeFsBasic failures.

The test fails reliably and quickly when run in a loop:

GOMAXPROCS=1 go test -run TestMemNodeFsBasic -count 1000 -failfast
