Re: [perl-win32-gui-users] LWP + Fork + Win32::GUI

[<ma...@mm...>]

i was under the impression that forking didn't work at all under
windows.....some problem with svtypes(? ). perl 5.8.0 threads and
win32::gui seem to work wonderfully tho.

fork under Win32 is emulated using IThreads (the only use of IThreads i=
n
5.6.1). They seem to work fine using pure Perl, but XS code is more
difficult (Win32::GUI is XS, and it also allocates Windows resources). =
Any
solution with fork + Perl 5.6.1 should be considered unstable unless te=
sted
a _lot_. And I still woulnd't trust it :)

IThreads in Perl 5.8 is supposed to be a lot better. So when ActiveStat=
e
releases a 5.8 distro, maybe we can make use for it.

I think one of the new things is that variables aren't shared between
threads unless you say so. And that, I hope, may solve the entire probl=
em
with non-reentrant XS code and such.

That would be _real_ nice!
