Syscalls are special, because they require values to be placed in
particular registers.  They're static or inline, mainly so they can get
the registers they need.  There's a bug in that valgrind is compiled
without -fpic despite being a shared object; the problem is that -fpic
makes it hard for the syscall functions to get the registers they need. 
I poked at it for a while, but didn't come up with a nice enough
solution to show off.

Obviously the problem is solvable, because glibc does it.
