I've used 'ktrace -p PID' to attach to tcsh.  I have a 43MB
file that contains nothing but

 56837 tcsh     PSIG  SIGCHLD caught handler=0x808375c mask=0x0 code=0x0
 56837 tcsh     CALL  sigreturn(0xbfbf1a60)
 56837 tcsh     RET   sigreturn JUSTRETURN
 56837 tcsh     PSIG  SIGCHLD caught handler=0x808375c mask=0x0 code=0x0
 56837 tcsh     CALL  sigreturn(0xbfbf1a60)
 56837 tcsh     RET   sigreturn JUSTRETURN
 56837 tcsh     PSIG  SIGCHLD caught handler=0x808375c mask=0x0 code=0x0
 56837 tcsh     CALL  sigreturn(0xbfbf1a60)
 56837 tcsh     RET   sigreturn JUSTRETURN
 56837 tcsh     PSIG  SIGCHLD caught handler=0x808375c mask=0x0 code=0x0
 56837 tcsh     CALL  sigreturn(0xbfbf1a60)
 56837 tcsh     RET   sigreturn JUSTRETURN

This file will grow without bounds unless I do 'killall gdb'

Please, revert the recent tcsh import.
