Should I re-start a fight about dropping COMPAT_SVR4? Because I keep finding bugs, and it's becoming tiring. Over time I've come across at least a good dozen of bugs in it, by just grepping through the tree searching for unrelated things. The last one is this [1], while working on kcov, exit1() is called but the proc mutex is not held.
The thing is just broken beyond repair. It is dead wood that consumes APIs and makes stuff harder to change, just like the network components we (thankfully) retired. [1] https://nxr.netbsd.org/xref/src/sys/compat/svr4_32/svr4_32_signal.c#661
