// sysconfig(_SC_OPEN_MAX) = -1 in upstream musl wasi.
// By undef'ing this constant, we cause Python to think
// that sysconfig doesn't know anything about SC_OPEN_MAX,
// so Python falls back to some default.  This is the right
// thing to do since (1) we can't change upstream wasi, and
// (2) wasi setting it to -1 is meant to convey that they
// don't know.   In fact, in our wasi-js implementation,
// we are setting the limit to 32768 since it takes about
// 0.2 seconds with wasi-js to stat everything up that bound,
// which seems acceptable for this sort of thing.
// The modern OS default is 2**20 = 1048575, and it takes
// about 0.5 seconds to stat everything up to that (of course,
// modern os's have better system calls so that stating everything
// isn't needed).  TODO: I'm also probably going to patch Python
// itself to replace its 256 default fallback with 32768 everywhere,
// though that can wait.
