for me, using kernel v1.99.8, libc v5.3.12, and grep v2.0, i get the

no memory left for grep

reprinting about every 20 seconds, and although i can switch VTs, the
system is utterly unusable and completely unresponsive. shift-scrllock
shows no swap memory left. the only way out is to hit reset (i waited
about 10 minutes).

i have 24 megs ram, with a 30 meg swap partition. 486dx2 if that helps

Why Linux? source code. POSIX. tcpip. job control. support from the authors.
drivers for most hardware. because one terminal or process is never enough.
forget the other O/Ss, i use Linux- the choice of a GNU generation.
