s!fails miserably!does not work at all!
Any platform without $Config{d_fork} will fail!
from perlport:
fork Not implemented. (Mac OS, AmigaOS, RISC OS, VOS, VM/ESA, VMS)
VOS and VMS are actively supported, and I know there are custum
build Win32
perls without fork().
This worries me!
The only fork we do is in IPC::Open3 - and we only really need
IPC::Open3 if the user requests that we merge STDOUT and STDERR (we
do that because passing both through a similar pipeline results in
STDOUT and STDERR being more in sync). I don't think we lose much by
making the merge option a nop on platforms that don't fork.
In those cases we can fall back to open(FH, "$command|") - which is
what Test::Harness currently does.
