That's probably a bug, as long as the underlying OS uses 64-bit file
offsets.  How does the 2Gb limit manifest itself?
On Solaris, the file grows until 2Gb, then:

    Fail: permission denied
    Action: commitAndReleaseBuffer
    Handle: {loc=/Home/stip/ketil/data/ug-250.seq.tmp_M,type=writable,binary=False,buffering=block (1024)}
    Reason: File too large
    File: /Home/stip/ketil/data/ug-250.seq.tmp_M

This file can be read from GHCI, but after I append "foo" to it and
try it agin, I get: 

    Prelude> x <- readFile "/Home/stip/ketil/data/ug-250.seq.tmp_M"
    *** Exception: failed
    Action: openFile
    Reason: Value too large for defined data type
    File: /Home/stip/ketil/data/ug-250.seq.tmp_M
...
From the manual pages to open(2):
O_LARGEFILE
           If set, the offset maximum in the open  file  descrip-
           tion  is  the  largest  value  that can be represented
           correctly in an object of type off64_t.

This is with SunOS 5.8.  Seems like it behaves quite similar to Linux
in this respect.
