Thank you for reply! But where to put JAM_SEMAPHORE? My schema projects look  
like that ('schemabuild' is a generator which takes *.imp as input and creates 
two files: *.sch and *.cxx):

import os ;
make myschema.sch : myschema.imp : @myschema : <location>. ;
make myschema.cxx : myschema.imp : @myschema : <location>. ;

actions myschema
{
cd $(>:D)
schemabuild $(>:D=)
}

lib schema
  : [ glob *.cpp ]
    myschema.cxx
  ;

Where to put JAM_SEMAPHORE to ensure that there will be no two 'schemabuild' 
executed concurrently?
