[fpc-pascal] simpleipc

[Brad Campbell]

G'day all,

I've been having a play with simpleipc.pp for trying to do cross-platform single instance detection.

Ordinarily it behaves perfectly, but I just noticed on Linux that it all comes crashing down if the 
server application crashes without removing the pipe.

I then have to manually remove the pipe to be able to start the server again.

Has anyone come up against this, or similar previously?
I'm somewhat stumped as to how to go about solving this as I can't find a reliable way of detecting 
a listener on the end of the pipe.

I figure the best way to go about it is to move from pipes to unix sockets, but this then starts to 
get considerably more complex.
