I doubt that it is just a recompile.
[that's a very terse answer.
perl is playing games when it execs another program so that it can do
reliable output capture. I know it's not a recompile. It's big.
However, I thought that there was a UnixLib version magic number in the proc
struct, and if the child finds that the parent's differs, the child ignores
it. If not, why did I think that?
Also, I wouldn't count me as the perl maintainer in any active sense.
I've effectively put the reins down. A guy called Richard Proctor was
going to take up the reins, but it's all gone quiet.
