What needs to be modernised about it? It's not like our disk i/o error  
code handles many more different error codes, nor are those errors  
much more specific. I remember the old discussion, but I never  
understood how the error reporting of the sockets code and the generic  
I/O code differed in a way that made the former worse than the latter.

IIRC the problem with removing socketerror would be that it could  
easily break existing code (given that socketerror is not overwritten  
by calls other than those from the sockets unit).
