There are two things seriously wrong with this response:
Firstly, even bugs in soi-disant "outdated" kernel features are bad,
and worthy of attention to fix them.
<flame>
Secondly, threads suck. They're currently fashionable, but it's by no
means clear that they're any improvement on asynchronous I/O.
I say this because threads encourage in the time domain all the same
kinds of aliasing havoc that you can get by being careless with
pointers in the spatial domain. It's way too hard to mentally model or
make provable assertions about the global state of a multi-threaded
program.
Monitors communicating through message queues are a much more tractable
way to control concurrency, as in Hoare's CSP or Mark Miller's E language
or (surprise!) Unix's classical process-connected-by-pipes.
