To this I would add that a number of commercial products currently available for FreeBSD depend on the Linux threads implimentation, notably Inktomis' depending on the future of the linux threads stuff, some diplomacy and vendor support may be necesary. What is the current status of the linux threads (Particularly with regard to SMP, which I recall was a problem)? How far from the userland bound original has libc_r moved ? Is the BSDi thread stuff completely seperate from all of this? -- GeoffB To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
