Yeah, AFAIK all recent Linuxen are well above the range of parameters
that I was suggesting (and even if they weren't, Linux is particularly
easy to change the SHMMAX setting on). It's other Unixoid platforms
that are likely to have a problem. Particularly the ones where you
have to rebuild the kernel to change SHMMAX; people may be afraid to
do that.

Does anyone know whether cygwin has a setting comparable to SHMMAX,
and if so what is its default value? How about the upcoming native
Windows port --- any issues there?
