Re: Tcl Thread Safety / Windows build

Thanks, I'm not trying to use threads explicitly but rather just need
to confirm that the Tcl dll handles reentrancy from multiple
simultaneous Tcl interpreters properly. A developer who has left our
company said that Tcl after 8.2 wasn't thread-safe and so we couldn't
upgrade to 8.4, but he never told us what he meant by that.

Interesting question. I certainly don't know, but I am interested.
Are there any particular sub-versions that should be avoided, because
of bugs in reentrancy?

My understanding is that any Tcl is safe to use in a threaded application
when each thread gets its own interp, and there is no communication
between those Tcl interps. Is my understanding right?
