According to the select(2) man page the FD_SETs and timeout struct becomes
undefined after select returned with an error. In libldap (e.g. in wait4msg()
and ldap_pvt_connect()) it seems possible that select is called more than once
without reinitializing the FD_SETs and the timeout struct. (Only if
LDAP_OPT_RESTART is set).
