Hi Levente,

An easy way to avoid that would be to write directly into the file stream,

Hm, I always thought they were.  A quick script I used to verify:

| ws rs |
nil assert: (FileDirectory default fileExists: 'writebuffered') not.
FileDirectory default deleteFileNamed: 'writebuffered'.
[ws := FileStream fileNamed: 'writebuffered'.
rs := FileStream readOnlyFileNamed: 'writebuffered'.
ws nextPutAll: '12345678901'.
"Assert only buffered, not written"
   nil assert: (rs next: 10) isEmpty.
"Force physical write"
   ws flush.
"Assert written"
   nil assert: (rs next: 10) = '1234567890' ] ensure:
[ ws ifNotNil: [ws close].
rs ifNotNil: [rs close] ]
