connection timeout controllable by a new printcap(5) capability named
`ct' (connectiom timeout), defaulting to 120 seconds (which is the
default TCP connection timeout).
Would anybody see a problem with merging all this into RELENG_2_2?
to POSIX.2. In particular:
- don't retry for ETXTBSY. This matches what sh(1) does. The retry code
was broken anyway. It only slept for several seconds for the first few
retries. Then it retried without sleeping.
- don't abort the search for errors related to the path prefix, in
particular for ENAMETOOLONG, ENOTDIR, ELOOP. This fixes PR1487. sh(1)
gets this wrong in the opposite direction by never aborting the search.
- don't confuse EACCES for errors related to the path prefix with EACCES
for errors related to the file. sh(1) gets this wrong.
- don't return a stale errno when the search terminates normally without
finding anything. The errno for the last unsuccessful execve() was
usually returned. This gave too much precedence to pathologies in the
last component of $PATH. This bug is irrelevant for sh(1).
The implementation still uses the optimization/race-inhibitor of trying
to execve() things first. POSIX.2 seems to require looking at file
permissions using stat(). We now use stat() after execve() if execve()
fails with an ambiguous error. Trying execve() first may actually be a
pessimization, since failing execve()s are fundamentally a little slower
than stat(), and are significantly slower when a file is found but has
unsuitable permissions or points to an unsuitable interpreter.

'slow' lookup if we get a YPERR_MAP (no such map in server's domain) error
instead of failing over on any error. In the latter case, if the 'fast'
search fails legitimately (i.e. the user or host really isn't a member
of the specified netgroup) then we end up doing the 'slow' search and
failing all over again. The result is still correct, but cycles are
consumed for no good reason.
Also removed the #ifdef CHARITABLE since the compat kludge is no longer
optional.

2) Use 555-#### examples to avoid potentially expensive accidents.
3) Escape @ in example pn capability (see related FAQ.sgml question).
Distribute all but the most fundamental malloc types. This time I also
remembered the trick to making things static: Put "static" in front of
them.

Now you can use one without entering the other and it will DTRT.
These changes just allowed me to do the most straight-forward new disk
installation I've ever managed with sysinstall.
