: it's against 1.3.77, already patched with Linus' p78.gz). Thanks a

: I'll post a patch on the linux-gcc list for Doug Lea's malloc-2.6.2.c
: (which is in libc-5.3.x) which makes realloc() use mremap() for large
: mmapped chunks.

: call mremap()..' and get an answer 12 hours later `OK, please try
: this patch..' Oops, must have been dreaming. [Please insert your
: workstation vendor for `SGI'.]
