alanc: what is postwait_post(3C)?!

docs.oracle.com/cd/E88353_01/html/E37843/postwait-post-3c.html ? (unclear what you'd use it for..)

it's how you send letters to Theo

obviously

sommerfeld: yes that one haha

[illumos-gate] 16765 loader: remove unused bzipfs, splitfs, pkgfs, ext2fs -- Toomas Soome <tsoome⊙mc>

the postwait_post thing reminds me that I was annoyed that there doesn't seem to be a way to use event ports to wait for a process to exit.

there does seem to bne something in there (postwait_post_deferred() with PWPOST_ATEXIT) but it's unclear if that survives exec())

sommerfeld: I was actually just talking to rmustacc about PORT_SOURCE_PID haha

Probably you would associate with a pid and it would return you the event when it was safe to call waitid() without blocking

yeah, PORT_SOURCE_PID would be one way to do it.

linux prior art in this space is pidfd_open() (which if we implemented you could then PORT_SOURCE_FD it)

presumably with useful guarantees about avoiding trouble from pid reuse (likely with similar caveats for pidfd_open() on linux -- you must call it on a pid you got from fork() before you have reaped it or did anything that would have allowed the kernel to auto-reap it)
