nlist using bfd

[Philippe De Muyter]

I noticed that the startup of my gdb is slow, and found out that it uses
nlist() to find the value of the `u' kernel symbol.  The native `nlist'
is slow, because it does a `read' system call for each `COFF' entry.

I think we should rather use `bfd' for that purpose, but I do not want
to reinvent the wheel, so here is my question : 

	Can somebody point me to an already written a `nlist' replacement
	using bfd, or sketch one off-hand ?

Thanks in advance
