I discovered late last night that libc_r implements only userland 
threads which seem to have issues with pipes (my code kept hanging 
inside the pipe i/o). I then discovered there are real system scope 
threads too, but they're in a different library called libkse.

You guys could seriously improve the documentation inside the man 
pages. Please! Just a two line paragraph would have saved me more 
than a day of work.

After linking to libkse and finding it really doesn't like coexisting 
with libc_r, I discovered the libmap.conf trick and it works now. 
Unfortunately I'm back to square one in that no gdb supports kse 
threads. This is a major problem as my code is heavily multithreaded.

Does this David Xu have some patch code for gdb around in some CVS 
repository? The only thing stopping me moving to FreeBSD as my 
primary Unix development platform is this as it's significantly 
faster than RedHat 9 on my system. If I could grab this support and 
get it mostly working, I could move to BSD permanently (in these last 
three days I find I prefer it to Linux for some unknown reason).

Cheers,
Niall
