I also discovered the hard way that glibc on Linux 2.4 kernels on some i386
platforms uses an implementation of pthreads that is incompatible with any
form of user stacks, including the kind that ucontext or pretty much any other
coroutine library uses... it's sufficient for your program merely to *link* to
the pthreads library to cause breakage.
