Dear monks,

I need to check if a file exists but never ever block on this check.
I tried -e first and then... 

sysopen my $fh, $file, O_RDONLY|O_NDELAY;
close $fh;

[download]
(NDELAY is the same as NONBLOCK)
...but it didn't work.

Test scenario:
Ubuntu computer with a sshfs-mounted path where the network cable was disconnected after the path had been mounted.

A external system call is no options as this must be OS independent (at least for Win, Linux, Mac).

alarm() doesn't work - the signal either doesn't fire or it's ignored.

Thanks
