I trussed an sshd (on Solaris 10 x86) and the failure seems to be polling FDs:

sudo truss -f `pwd`/sshd -D -e -p 2022 -o useprivilegeseparation=sandbox
[...]
1788:  write(5, "\0\003\f\n1414 ND4 % 5 [".., 784)     = 784

21788:  read(5, "\0\002AC\n14A8F8B912   D".., 8192)     = 688

21788:  read(5, 0x080457C0, 8192)                       Err#11 EAGAIN
21788:  write(9, "\0\0\0 A\0\0\001\0\0\0 9".., 69)      = 69

I'm wondering if pollsys uses a descriptor under the covers (eg for
/dev/poll).  Not sure what can be done about it though.

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
