ISSUES:
An example and better explansion on how to specify a user's login
class in /etc/master passwd is needed.
(As I don't seem to be specifiying it right, I can't do it).
can return UNIX errnos. When UNIX errnos catch up with FTP status
codes (e.g. at 100) a new way will have to be found to tell which
is which.
This allows fetch to print errors like
fetch: ftp.fu-berlin.de: No route to host
instead of
fetch: ftp.fu-berlin.de: Unknown error
nuked file descriptor. This is probably why sysinstall's ftp xfer
occasionally SEGV'd if you left things alone for a long time and
the timeout code got called. Whoops!

plain 0 should be used. This happens to work because we #define
NULL to 0, but is stylistically wrong and can cause problems
for people trying to port bits of code to other environments.

an unimplemented syscall returned ENOSYS, rather than EINVAL. I have run
statically linked code with this wrapper and it does appear to work fine
on 2.2-stable which doesn't have poll(). ktrace shows the poll syscall fail
once and the fallback to select() working.
if necessary. This removes the need to malloc large fd_set's for selecting
on high fd's (larger than FD_SETSIZE at libc compile time).
The syscall adaptive stuff only happens on the very first call. SIGSYS
is masked, and if the call to poll fails with ENOSYS, then we use select
for the life of the program. If poll does not fail with ENOSYS, then we
always use poll and skip the once-off signal masking gunk.
This may be overkill, but it saved my neck a few times while working on
multiple different sets of kernel sources, some with poll, some without.
things like libskey.so to be dynamically self contained.
Things like md5(1) where speed is critical should still link with libmd.a,
but for things like login, where it's a once-off call if skey is used, it's
not worth the hassle.
