From what I saw in DDD, it's a SIGIO. I have been investigating
the problem a
little further since my last post and it appears that
`slow_down_interrupts'
does not disable SIGIO correctly at least on RedHat 6.0 Linux.
Adding a pair of EMACS_{UN}BLOCK_SIGNAL (SIGIO); around calls to `ldap_result'
solves the problem. Therefore I believe `unrequest_sigio' (called from
`slow_down_interrupts') is not doing its job correctly.
