Replace some blind timeouts with actual synchronization. Improve performance on some slow tests. Tweak some of the remaining timeouts. This still isn't good enough to get 'make -j9 check' working reliably on Cygwin for me; I think some Cygwin/ Windows scheduling issues remain.

# This is a regression test for a BSD pty bug in Mosh. On

# FreeBSD/OpenBSD/OS X, a pty master can block on read() after
|
|
# select() has informed us that there is data available, if a ^S is
|
|
# written to the pty master between the select() and the read().
|
|
#
|

# Unfortunately, everything attached to the pty gets stuck when this
|

# happens. If this tests fails, you will need to do some manual
|
|
# cleanup with kill -9.
