...F0000, 0146008 ) and later a crash somewhere deep in libwsock32 (the trace is rather weird) ... I guess the problem is the heap, not wsock itself. Any idea what that could be? All the above was tested with MinGW-3.1. Any ideas? Is that a MinGW bug or something I did? ;) Thanks.

...or an interactive process such a SIGINT is just swallowed, with a newline outputted to the terminal. But apparently, for this background process, it is not swallowed, and it is triggered later.

Presumably one could stream over the data twice, the first to get the size, without storing the data. Slower but more memory efficient, unless I'm missing something.

Dear R users / devs, There's been requests in the past for a text editor built into the Rgui for Windows, from which code can be submitted to the R console. Something along the lines of the script editor in S-Plus. Currently Rgui can only display a file read-only in a pager. As far as I can tell there's been little motivation to implement an editor, as most developers use (the
