[9fans] fossil 'sync' lockup?

Hi, I executed the fossil 'sync' command when my terminal was under moderate I/O load earlier today. Fossil seems to have locked up. Has anyone seen anything like this? I have a dump of the first 256mb of kernel memory and all physical memory. Are there any structures that are kept at reasonably

There's a talk Doug McIllroy gave where he joked about how he basically invented (or rather, discovered) recursion because someone said ``Hey, what would happen if we made a FORTRAN routine call itself?'' IIRC he had to tinker with the compiler to get it to accept the idea, and at first, no one

Well I can think of 3 operating systems written in Haskell now. One was an executable specification for validating a secure L4 implementation. One is hOp, and then there's also House, based on hOp. Keep in mind that House and hOp both used the ghc runtime (written in C) as a base. I would
