sink() does not seem to release the file
To add to that, this behaviour has been changed in the R-patched version
(and hence for 1.2.1): from NEWS/BUG FIXES
o Explicitly close files opened by sink() for OSes (such as
Windows) that benefit from it.
In other words, sink() will close the connection for you.

I run Win2000, and when I try to write to a file and later use it it seems that R 1.02.0 has a firm grip on it:

When I use sink(filename) to save the results of the run, the file does not seem to be closed or released back to the OS after I issue the "sink()" command. Here is a baby example:
sink works on connections, not files, as from 1.2.0.
sink("test.txt")
tdta <- data.frame(x = x <- 0:10,y = 2 * x + rnorm(11))
print(summary(lm(y ~ x, data=tdta)))
sink()
At this point (even after refreshing the Explorer window) the filesize of
"test.txt" is listed as 0 bytes, and as long as Rgui is running, I
cannot delete the file. Emacs cannot read the file (but Notepad can). This happens both in the gui
and when the commands are in a file run via "source()".
Yes, but what is the bug exactly? The connection is still open so you can
switch output back to it. If you want different behaviour, you can open a
connection and close it yourself. As in
zz <- file("test.txt", "w")
sink(zz)
tdta <- data.frame(x = x <- 0:10,y = 2 * x + rnorm(11))
print(summary(lm(y ~ x, data=tdta)))
sink()
close(zz)
