Put the cron stuff in a file, then:

2 4 * * * mhlock /usr/local/libexec/cronmhstuff

mhlock grabs the lock, runs whatever command was fed it, then releases the 
lock.  It would be the MH equivalent of FreeBSD's lockf(1).

As long as the mhlocked cron job is running, interactive commands would block 
waiting to acquire the lock.
