I've started writing a (single-file) FIFO VFS plugin. I have gotten it to compile, but I still need a little help.

How should I test my plugin? I'm not aware of a good run script to base a test on.

How should I register signal handlers? I can use a list of List_element<Signal_context_capability>, but that requires extra dynamic memory allocations. How should I handle this to properly account for memory?
