in reply to RSperl & threads

Caveat: I know nothing about RSPerl, other than it embeds one interpretter in the other.

Since each Perl thread starts a new interpretter, its unclear whether an R interpretter created in the main thread will get cloned into all the children, or each child will get a brand new R interpretter instance.

Assuming you revert to the original approach, you might try cranking up the per-thread stack size, and see if that corrects the error message. Note that doing so will reduce the number of threads you can start.

[Corion]: (b) would be cool. I've thought about this doing Pod editing, and even simply regenerating/live updating the browser makes things much more interactive
[ambrus]: modern computers have way enough processing power to allow this, at least for geeks who are willing to spend a few weeks to learn a tricky new user interface like vim
[Corion]: ambrus: Well, for mathematical notation, I find blackboard much more convenient than a computer. But when inserting text or moving text around, the computer wins obviously
[ambrus]: But either of these is a big problem in practice, so I'd need to spend like thirty years of my life to solve (a) and five more years to solve (b)
[ambrus]: Corion: yes, CURRENTLY the blackboard is more convenient
[ambrus]: and it's not like I want to ban blackboards anyway
[ambrus]: you already have blackboards and a canvas for projector or overhead transparencies (or positive film slide projector, not used for maths) canvas in the same lecture halls today, and switch in a few minutes between presentations,
[ambrus]: they're only difficult to use together.
[ambrus]: overhead transparencies are a nice convenience by the way that mix the two slides, because you can write them in advance and edit them during the presentation easily. but they're not very much in fasion these days.
[ambrus]: you can even print them.
