Comment (by pulkomandy):
The locking was indeed different, but the new locking was not working
properly, there were race conditions. This is what I changed, and now the
"new" tty system uses the same locking design as the old one.
As far as I can tell, the only difference now is that the old tty system
has a preallocated hardcoded list of ttys. The new system can allocate
them dynamically.
I think the static list is needed for beos api compatibility. Our Terminal
expects pty/tty devices to pre-exist in /dev.
I think the old module could be stripped to do just that: provide these
hardcoded pty/tty pairs in /dev. It could do so by using the new generic
tty module. And maybe we can rename it to pty (pseudo-teletype) to make it
more clear what it is used for: basically anything not related to an
actual serial port.
