The problem is that zsh will "freeze" somewhat, but
not entirely, predictably.

Here's the tail of an strace.

rt_sigprocmask(SIG_BLOCK, ~[], ~[HUP KILL STOP], 8) = 0
rt_sigprocmask(SIG_SETMASK, ~[HUP KILL STOP], ~[KILL STOP], 8) = 0

ioctl(10, 0x4004541e, [6889])           = 0

rt_sigreturn(0xa)                       = 0

make check will not get through A01grammar.ztst.  More
specifically, it freezes at the "emulate -R zsh"
in ztst.zsh.

When sourcing someone's .zshrc, it freezes at
[ "`id -u`" -eq "0" ]
or at
eval `dircolors -b`

Any ideas?

Other shells don't seem to suffer from this.
