I am sorry to here of this, but I know what you mean about microsoft.
My and co-worker's code for doing full taskfile access under linux was
rejected here but is being used in MicroSoft Whistler 2001. They are
quick to grab the very best of Linux and adopt it for their own.
To change NR_TASKS, can one just redefine it somehow in the top

just an aside on asynchronous i/o: concurrency by asychronous I/O actually
predates concurrency via thread-like models, and goes back to the earliest
OS-precursors. Early work on thread-like concurrency models were, in part,

If you need concurrency, you need concurrency, and any existing model is

We do a single copy/checksum from user space. You have to do the copy because
the packet may not be DMAable, may not be aligned for most PCI hardware

**ALL** Netware network drivers support a scatter/gather proramming
interface, whether the hardware does or not. In NetWare, the drivers
get passed a fragment list in what's called an ECB (Event Control
