And the problem, some process will have to look after all the open filehandles, sockets etc. Perhaps by hibernating these will time out, which is bad. Also, what about scripts that are dependent on signals - you could hibernate the script before it was due to catch a signal, which is painful to debug. Signals are already a nightmare as it is, thank you. IMSOHO this is impossible to implement sucessfully, without turning Perl into a non-portable, complex and slow language. Ask the experts, not the beginners list!
