** Bug: Memchan: [[`[fileevent] readable`]] (FIXED) **

The following script illustrates a problem with Memchan:  it stops generating
'''readable''' events too early.  The same problem was reported (10 years ago!)
for [memchan].  Maybe it needs to be fixed there, too.

======
#! /bin/env tclsh

package require tcl::chan::events
package require tcl::chan::memchan

proc copied {args} {
        puts $args
        set ::done 1
}

set chan [tcl::chan::memchan]
puts -nonewline $chan [string repeat a 50000]
seek $chan 0 start
set chanout [open zout w]
fcopy $chan $chanout -command copied

vwait ::done
======

[AMG]: This bug was fixed one day after your post [http://core.tcl.tk/tcllib/info/fc756af7855c811d].

[PYK] 2015-05-03: Yes, I probably posted it here first, and then went on to
report it via a ticket, along with the fix.  The only outstanding questin is
whether it needs to be fixed in [Memchan] as well.
