--- Comment #5 from Tom Tromey <tromey at sourceware dot org> ---
Ok, see this comment:

https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=gdb/linux-nat.c;h=8840dbe3f75ef55929343f3eebcd3817d1d59c1b;hb=HEAD#l179

Supposedly gdb will fall back to ptrace if writing to /proc/mem fails,
but it sounds like perhaps this isn't working, or maybe the fallback
has to be extended somehow.
