would refuse to start new children because count_idle_servers() will
count those SERVER_STARTING entries and will always report that there
are enough idle servers.

dump core on SIGSEGV regularly, HPUX, version: 10.10, Apache 1.2b4.
Ben mentioned that the symptoms looked like a stack corruption.

I think this is being caused when an initial call to select or accept
fails (for any reason) and the code attempts to reuse the same parameters
even though they were modified by the call.  In any case, we should be
reinitializing the parameters before each call even if this isn't the
cause of the problem.  Also removes potential infinite loop in call to accept.
