Summary: vwait loops forever

Initial Comment:
platform: sco 5.0.2, gcc 2.95.3

Problem behavior:

Infinite loops occur in `vwait' command at least in
`basic.test' item 26.1 and `http.test' 3.3.  Call
chain: Tcl_VwaitObjCmd -> Tcl_DoOneEvent ->
Tcl_WaitForEvent -> select.  `select' system call
always returns -1 and sets errno = `EINVAL'.  So `file
writeable' event handlers are never invoked, `select'
called again.

Expected behavior: see test files.

Further info: this is observed only if tcl build dir is in
NFS filesystem.  On local filesystem it works normally. 
Anyway, `EINVAL' should cause Tcl_WaitForEvent to return -1
and thus avoid infinite loop.
