Re: {Spam?} Re: Cannot start Spyce 2.1-2 web server

It looks like your VSZ has a buggy count of memory used by threaded
processes -- each thread = about 10k, which is not actually the case,
since you will remember that one point of threads is they all share the
same memory.  I'd find a host that doesn't do that -- even if I patched
2.1 to have a threadless mode like 2.0, it would be basically useless
for production since any slow request will block everyone else from
using your app.  I'm pretty sure westhost.com doesn't, for instance, but
it's been a while since I used them (switched to a dedicated machine).
