- Not really. The depths of the kernel usually are not reentrant, in order to
- simplify things so the O/S is finished and out the door quicker. One notorious
- violation is Sun NFS, which hogs the machine anytime it feels like it. You need
- a fast SPARC (2 or later) and lots of memory or else NFS bogs the machine down
- big time. I use an IPC with 8 megs at work, and anything I run often I copy to
- the local disk. It makes a big difference.
