ACTION idly wonders if there could be a cottage industry for algoritms that scan the heap sequentially, even in multiple passes, to make use of the ~15GB/s bandwidth for independent reads

though I guess pkhuong is a leading authority on parallelizing memory accesses so probably any low hanging fruit has been picked :)

In any case, I'm happy to report that LUL is running SBCL in their production environment, so there is potential blame to share in the future.

Does (format t "RUN: gdb -ex \"handle SIGSEGV pass noprint nostop\" -ex \"attach ~a\" -ex \"b *536873568\" -ex \"continue\"~%" (sb-posix:getpid)) (sleep 10) count as printf-debugging?

A nice side-effect of not handling every exception is that stepping with GDB seems to work now.

Mixed mingw and msvc ffi code is still a pain, though now that I know a little bit more about what mingw/msvc/sbcl frames look like, a solution might present itself.

luis: my mother used to work on scheduling and logistics for London Transport. We used to joke that it was her fault that the buses always came clumped in threes
