Hi again

The stock gethostby* name resolution lookup routines in perl are making blocking function calls. Does any one know of any module that uses the non blocking (reentrant) gethostby*_r function calls? NET::DNS blocks as well :-( This is of particular interest in environments where name resolution can take several minutes to resolve, causing a hang.

The normal catching of the alarm signal does not occur as it is a single op. This forces us at times to use unsafe signal handling which is not at all preferable.

I am curious as to why Perl doesn't use the reentrant gethostby*_r() if they are available... does anyone have any idea why?
